History:
The path of the initial Northwestern Elevated Railroad line, from Lake and Wells Streets to Broadway and Wilson on the what was then the far north side, was cleared in 1895 and erection of the steel was begun January 23, 1896. Several financial difficulties delayed construction several times, a few times necessitating extensions of the company's franchise. All night shifts were eventually required to complete the structure on Christmas Day 1899, days before their deadline to begin service. But Center Street (Armitage's original name) and most of the other stations were incomplete December 31 and, after some finagling, another extension was obtained. Center was completed in early 1900.

The dual side platforms at Armitage are covered in the center by two peaked-roof canopies of steel support with a gently-curved bracket and intricate latticework, covered by a corrugated metal roofing. Originally, these covered about half the platform length, but the platforms were subsequently lengthened multiple times to allow longer trains to berth. Many sections of the original platform area still has original railing, which consisted of tubular railings and posts with panels of decorative, vaguely diamond shaped metalwork inside. The platform extensions have plain wooden railings.
Under the initial Northwestern Elevated configuration, Armitage, whose platforms are on the outer tracks, was a local station, inaccessible by the expresses utilizing the inner tracks. After the State Street Subway opened in 1943 and the route configurations were overhauled in 1949, Armitage became a station on the Ravenswood Line, initially serving only "A" trains under the skip-stop express scheme, but eventually called at by all trains.
An interlocking tower was added over the inbound platform in the early 1940s to observe and control the new crossovers at the entrance to the State Street Subway. Armitage Interlocking is no longer controlled from Armitage Tower, however. Armitage Tower was turned into field offices, first for the North District transportation section and later for the Signal Department.
Brown Line Capacity Expansion Project
By 2004, ridership had exploded on the Brown Line -- an 79% increase since 1979 and a 27% increase since 1998 -- that during peak periods many trains were at crush-loaded, resulting in commuters left standing on platforms unable to board the loaded trains, sometimes waiting as one or two trains passed before they were physically able to board. The problem in large part was that all Brown Line stations could only accommodate six-car trains (with the exception of Merchandise Mart, Chicago, Fullerton and Belmont, which could already hold eight-car trains), which, along with the limitations of the cab signal system, limited the line's capacity.

On April 13, 2004, the CTA® announced that it had officially received a Full Funding Grant Agreement (FFGA) from the Federal Transit Administration (FTA). However, in May 2004, CTA® received construction bids for the project that substantially exceeded the budget. As such, the Chicago Transit Board voted on June 9, 2004 to reorganize the project into several discrete pieces to help attract more competitive construction bids. Station renovation work was modified and grouped into five separate packages according to location to help reduce the overall cost of station construction. Armitage station was grouped with Sedgwick, and Chicago in a bid package, all of which were designed by the same consultant, Gonzalez Hasbrouck Architects. Station designs were also revised to reduce costs. Most changes concentrated on non-customer areas such as reducing the size of janitor closets, employee restrooms, electrical rooms and communication rooms. Other areas that were studied for cost reduction were standardizing common station elements, the use of less expensive materials, canopy designs and coverage, and temporary station closures to provide contractors better access to the sites.
The Armitage/Sedgwick/Chicago contract was the second of the reorganized station packages to be bid out. At the September 14, 2005 board meeting, a $45.5 million contract for the renovation of these stations was awarded to FHP Tectonics Corporation.
Station Design
|
This artist's rendering shows the street-level design for the renovated Armitage station. The historic station house will be renovated with an addition built behind and next to it. The historic platform canopy is visible at platform level above. The Brown Line-standard railings and modern lights shown here have since been revised to retain and fill-in the historic railings and to use more sympathetic light standards.

The addition on the rear of the station house was connected by removing the rear wall of the historic structure. The addition is not a solid structure, however. The front elevations of the expansion, which flanks the historic station house and projects to the east from the rear of the building, are tall screens consisting of metal grilles rather than solid walls. The rear expansion features a solid back wall fronting the various ancillary equipment rooms behind it and decorated with a mosaic mural, concrete floors, and a suspended metal ceiling with recessed lighting. New, wider stairs and elevators take customers to the boarding platforms.
The dual platforms were renovated with new decking, railings, lighting, signage, and other fixtures. The elevator towers, located at the middle of the historic canopies, are clad in black glazed tile within the spaces framed by the steel skeleton, which remains visible in the corners and crossbeams. The black tile allows the elevator towers to be less noticeable and fade into the background rather than contrasting with the historic canopies. The northbound tower is located outboard of the platform, while the southbound elevator is located within the confines of the platform, and projects through the roof of the historic canopy, due to space constraints caused by the adjacent building.
The existing original, historic canopies were retained and refurbished, stripped of decades of paint, repainted dark brown, and topped with new corrugated metal hipped roofs. The new railings are a standard design for the rebuilt Brown Line elevated stations, with thick tubular top and bottom horizontal members with rectangular panels with a grid pattern cut out. The exceptions are the sections over the street, which have the same tubular frame but whose grilles are reproductions of the original Northwestern Elevated diamond grilles. The railings and light poles, as well as the other new metalwork, are hot-dipped galvanized, but over the street are painted brown to harmonize with the surrounding Armitage-Halsted Historic District. The light poles are integrated into the railing posts, with modern luminaires on most of the platforms and gooseneck lights over the street. Canopies over the new stairways feature enclosures of galvanized steel frames, panels matching the design of the platform railing grilles, and flat roofs. The platforms are finished with windbreaks integrated into the railing system, with the glass panels protected by metal grilles matching the railings and station name signs integrated into the back panel, benches with sandboxes integrated into them, A/V signs suspended over the platforms on long horizontal arms, and Transit Information panels. Auxiliary exits are provided to the south side of Armitage Avenue, across from the main entrance, to allow for more egress capacity and better connections to eastbound #73 Armitage buses.
Other improvements included new signage; electrical, communications, and HVAC equipment; new customer heaters on the platforms; and a new public announcement system.
Station Renovation Work
During station construction, Armitage, Sedgwick, and Chicago will remain open on weekdays, but may experience up to six weekend closures during the construction period when all three stations will be closed at the same time to allow construction crews unlimited access to station platforms.
Work at Armitage station contract began in autumn 2006. Early work included preparatory work at the station site, as well as work at 939 W. Armitage, a historic building adjacent to Armitage station on the east side of the station on the south side of Armitage Avenue. The masonry building with an ornamental front facade is a contributing structure in the Armitage-Halsted Historic District and thus was required to be at least partially preserved. However, the new, expanded northbound platform must occupy part of the footprint of the building. So, the west half of the building was demolished and the east half preserved, with a new west elevation built to enclose the building and allow it to continue to be used, similar in fashion to how the backs of several buildings were removed for the construction of the State Street Subway incline in the same area during the early 1940s. During autumn, crews demolished the interior of 939 W. Armitage, preparing for the demolition of the west half of the building.
Also during autumn 2006, crews installed the new steel stringers for the extended platforms, beginning at the far south end of the platforms and working north. Only the southernmost hundred feet or so were initially installed, with the wood decking applied to these sections beginning the last week of December 2006.

Installation of additional stringers, joists, and decking for the platform extensions did not resume until spring 2007. By the end of April, the stringers had been installed all the way to the south end of the existing southbound platform, with decking covering most of that length. Steel had also begun to be set for the auxiliary exit stair from the southbound platform to the south side of Armitage Avenue.
Also during spring 2007, crews began erecting a temporary entrance on the south side of Armitage Avenue, in the location of what would ultimately be the auxiliary exits, to allow the main entrance at Armitage to close for renovation. During March 2007, a temporary wooden station house was constructed, consisting of a simple wood frame structure with plywood walls and a flat, slanted roof. Inside, a customer assistant booth was built-in as a room with windows and a door to interact with customers occupying the southeast corner of the interior. The building sat dormant for several months as other work continued.
A second linecut was performed at the south end of the Brown Line during the first weekend of May 2007. However, unlike the first south-end linecut in December 2006, trains were allowed to service Armitage station, terminating at the southbound platform, changing ends, and then returning back to Kimball. Trains were crossed back to the northbound track through Armitage Interlocking. With no rail service to Sedgwick, Chicago, and Merchandise Mart stations from Friday night, May 4 through the end of the Sunday, May 6 service day, bus shuttles operated from Fullerton to Clark/Lake. During the May linecut, crews erected the steel frame for the northbound platform elevator tower, removed the old, narrow wooden platform at the south end of the northbound platform and installed new steel stringers and joists to connect the new platform extension already built south of the station to the existing full-width platform over Armitage Avenue. When the station reopened Monday morning, May 7, the north end of the southbound platform utilized part of the newly-built full-width platform.

In late May, crews began installing masonry walls around the steel elevator tower frame that had been erected during the linecut a few weeks earlier. First cinder block was installed, then the surfaces were clad in black tiles. Masonry work continued into mid-June.
During June, work accelerated to prepare the new platforms and the temporary entrance for service. During mid-June through July, work continued to install new permanent railings at south ends of the new platform extensions and around the new auxiliary stairs. Crews installed the canopy over southbound auxiliary stairway and continued to install railings, grilles, windbreaks, and other platform fittings. In late June, the sidewalks for temporary station entrance were poured.

A week later, on Sunday, July 22, the fare equipment from the old Armitage station house was relocated to the temporary station house across the street. Bus fareboxes were temporary used while the turnstiles were disconnected and moved. At 5am, Monday, July 23, 2007, the temporary station entrance on the south side of Armitage Avenue came into use. Passengers access the platforms via the new auxiliary stairways installed during the previous two months. The old station house was fenced off and the stairs down from the platforms to old station house were barricaded. A new barrier was placed between the stairs on the old section of platform, taking another 100 feet or so of the old platform pout of service. Additional signage and platform furniture was relocated to the new platform. The temporary entrance is expected to be in place through early 2008.
With passengers relocated to the new platforms and temporary entrance, work accelerated on the new facilities on the north side of Armitage Avenue. In mid-July, crews begin selective demolition of the historic station house and demolition of the north- and southbound platforms north of the canopies. In early August, the new, permanent station name signs were installed on the newly-opened south platform extensions, replacing the old KDR station name signs that the contractor had temporarily mounted on the new backer plates with temporary wooden mounting brackets. On August 7, the contractor erected the structural steel framework for the elevator tower on the southbound platform. During September and October, crews installed the black masonry panels on the elevator tower exteriors, while work on installing the elevator cabs and equipment continued into spring 2008.

Work continued throughout the facility in 2008, with the installation of the prefabricated staircases from the station house's paid area to each platform in early January. Between January and April, the permanent steel back railings were installed in the middle and north sections of both platforms, as were the permanent light fixtures. In February, the reproduction historic railing grilles over Armitage Avenue were installed. During the week of March 17, gooseneck light fixtures were installed on the sections of both platforms over and visible from Armitage Avenue. Other platform work included installation of blue tactile in late March, LED A/V signs in March and April, benches and gap fillers in April, and various signage through late winter and spring. Down in the station house, work continued throughout winter and spring to build out the new fare collection area and auxiliary rooms. Work included installing masonry and tile cladding on the rear wall and rooms, various electrical, communications and other systems, new flooring in the station house and paid area, plaster and woodwork in the historic station house, the new customer assistant booth, signage, and a new drip pan over the sidewalk in front of the station entrance.

With construction nearly complete at Armitage station, the main station entrance reopened on Thursday, June 5, 2008. Upon the renovated main entrance reopening, the elevators came into use and Armitage became the 82nd of the CTA's® 144 station to become accessible, with other ADA-compliant features including an accessible turnstile, tactile platform edging, gap fillers, TTY telephones and Braille signs. At the same time, the temporary entrance located on the south side of Armitage Avenue was closed and subsequently dismantled in the weeks after. The stairways down to the south side of Armitage were also closed in mid-June to allow for the installation of rotogates on the platforms and conversion of the stairs into auxiliary exits.
Modest work continued at Armitage station after the reopening, as the contractor completed landscaping and various other punchlist work. After the main entrance reopened, reproduction oak handrails were installed on the railing around the stair from the southbound platform to the station house. During July, the contractors installed the drip pan and lighting over the plaza in front of the auxiliary exits on the south side of Armitage, across from the main entrance. They also poured a new concrete deck and installed brick planters and signage in the plaza and installed the exit rotogates at the top of the exit stairs.
The Brown Line Capacity Expansion Project Full Funding Grant Agreement with the federal government requires that the CTA® complete the entire project by the end of 2009.
