The original Logan Square station served as the terminal of the Northwest branch of the Metropolitan Elevated (and successor Logan Square branch of the CRT and CTA ) for 90 years, opening on May 25, 1895. The complex included a double-track, two platform station, a car inspection shop, and a storage yard. In the late 1960s, it was decided the Logan Square branch was to be extended passed its namesake terminal for the first time, necessitating the removal of the old elevated station, which closed concurrently with the new extension opening on February 1, 1970.

The extension of the Milwaukee Line of the West-Northwest Route (the forerunner of today's Blue Line) reached its new terminal at Jefferson Park via a new subway and the median of the Kennedy Expressway. As a result, the tracks had to descend into a new subway under Milwaukee and Kimball avenues before the old Logan Square terminal, requiring the construction of a new subterranean station to replace the elevated terminal. The new station, located just to the northeast of the old terminal, is actually immediately to the north of the station's namesake public square.

The design of station was carried out by Skidmore, Owings & Merrill, who developed a modern, functional form. Skidmore took the Kennedy-Dan Ryan ("KDR") project in a unique direction, designing all aspects of the new lines to harmonize in both shapes and materials. All windbreaks, dividers, and ticket booths were stainless steel. The shape of everything, from the buildings to the agents' booths, to the trashcans, flowed together into a seamless design philosophy, which perfectly captured the boxy, purely functional International Modern style for which Skidmore is so well known.

The fare controls are at a mezzanine level, with entrances from multiple sides of the streets above. The station has two exits, one at Spaulding/Milwaukee (2732N), serving Diversey (2800N/3400W), the other at Kedzie/Milwaukee (3200W/2600N), at Logan Square. The mezzanines are not enclosed, as in the State and Dearborn subways, but are cantilevered over the platforms, and thus functioned more as an open deck overlooking the track level.

The island platform is spacious, with a column-free platform obtained by using a box-girder construction. The walls of the station mezzanines and platform areas were off-white brick (later discolored to a tan hue), with white concrete coffered ceilings and fluorescent lights recessed in the coffers. Further down the platform from the mezzanines, the ceilings become arched concrete.

An off-street bus terminal is located at the Kedzie entrance on the northeast corner of Milwaukee and Kedzie, with one of the stair/escalator accessways from the station mezzanine leading directly to the bus terminal. The other stairway leads to the west side of Milwaukee Avenue.


Accessibility and Other Upgrades

In 2000, the CTA began construction on a number of improvements to the Logan Square subway station. These additions included two new elevators (one from the street to the Kedzie mezzanine and one from the Kedzie mezzanine to the platform), additional mezzanine floor space, and a relocated customer assistant kiosk and platform-to-mezzanine stairway. By March 2001, the sidewalk at street level had been modified to accept the new elevator. The steel work for the mezzanine extension over the platform for the new stairway and elevator was underway and nearly complete by the middle of the month. Also underway were the construction of new CTA personnel restrooms, maintenance rooms and customer assistant kiosk.

In April, the new janitor's closet and revenue room, as well as pouring of a new sidewalk at street level was completed, as was the extension of the Kedzie mezzanine floor over the platform. Work on the elevator tube framing and new customer assistant kiosks then progressed, with construction of the new interior and exterior elevators, the kiosks, and maintenance/electrical rooms all scheduled to be substantially completed in May. By July, the elevator shafts and housing on both lifts had been completed and the sidewalk around the elevator at street level had been re-poured. The new CA kiosk and flooring in the mezzanine area was finished as well. Completion of outside and inside elevators was underway. The completion CTA employee restrooms, maintenance rooms and mechanical room was also in progress. The new stairs between the platform and mezzanine were complete. Final work on the elevators, mezzanine and some platform signage, auxiliary rooms, and other features was completed in late Summer 2001.

New station name signs, following the Green Line Graphic Standard, were installed at four Blue Line stations in late 2002/early 2003, including Logan Square. The fabrication and installation of these signs was actually the continuation of the renovation work that was completed here in 2000-01. New station name signs were installed around February 2003 and replaced the original signs on the brick walls outside the tracks, opposite the island platform. Here, as at a few other stations, the tabs (whose color is used to denote the lines serving that platform) have the names and directions of the various exits in them. The tabs at Logan Square are an improvement of sorts, in that the streets listed in the tabs are actually more accurate than in the KDR signs they replaced: in the original signs, the exits were listed as "Kedzie" and "Diversey", though Diversey is actually a block north of the north exit; the new signs list the exits as "Kedzie" and "Spaulding" (where the north exit actually deposits passengers). In this sign installation, the new Green Line Graphic Standard signs were initially only placed outside the tracks, facing the platform, but not on or over the platform. At the same time, the symbol signs that were posted on the outside walls were removed. Later, station name signs were also placed down the center of the platform, hung overhead on newly-installed brackets suspended from the arched ceiling.


Logan Square Gets 'Renewed'

On September 20, 2011, Chicago Mayor Rahm Emanuel and CTA President Forrest Claypool announced a new CTA station renewal initiative designed to provide a facelift to 100 CTA rail stations over the following 12 months. The first station to receive a renewal was the Logan Square Blue Line station, where the Mayor, Alderman Colon and Claypool made the announcement.

The initiative, performed by work crews called the 'Renew Crew' comprised of different trade workers, focuses on providing repairs in a more efficient way, creating a cleaner, brighter and more appealing station that improves the customer travel experience. Different stations will receive different scopes of work depending on their needs and the available resources, but generally will fall into two categories: basic renewals and expanded renewals. Stations receiving a basic renewal will see more general maintenance-type activities, such as cleaning and power-washing; paint touch-ups; minor repairs to concrete, masonry, metalwork, or woodwork; signage replacement; cleaning or re-lamping of light fixtures; and cleaning and repair of drains and gutters.

Stations receiving an expanded renewal may see a variety of additional activities, depending on the needs of the station. Logan Square was one example of an expanded scope, which included extensive cleaning of the brick tunnel walls and ceiling, water management to prevent and mitigate leaks behind the tunnel walls and ceiling, installation of additional light fixtures and directional line diagram signs on the subway platform tunnel walls, refurbishment of the escalators at both the Kedzie main entrance and the Spaulding auxiliary entrance escalator, and the upgrading of 19 existing security cameras with digital high definition cameras.


Your New Blue: Station Improvements

On December 5, 2013, Mayor Rahm Emanuel and Governor Pat Quinn announced a comprehensive improvement plan for the Blue Line O'Hare Branch (including the northern portion of the Dearborn Subway), an overhaul that will provide faster travel times and updated stations while creating more than 1,300 jobs.

The $492 million plan, called Your New Blue, includes several track and station improvement projects along a 12.5-mile stretch of the Blue Line between the Grand and Cumberland stations, as well as upgrades to the signal system between the Jefferson Park and O'Hare stations. The overall Your New Blue program, beginning construction in 2014, is a package of several discrete projects ranging from station improvements to track renewal, signal replacement, traction power upgrades, and subway tunnel water mitigation efforts.

Logan Square is one of the stations planned to receive improvements under the program. The scope of these improvements was intended to increase the useful life of the station rather than perform a full renovation. The work included waterproofing, electrical work and lighting improvements, refurbishing the two elevators, and refreshing the mezzanines, platforms, auxiliary entrance plaza on the south side of Milwaukee Avenue and auxiliary entrances on Spaulding Avenue through deep cleaning and painting. Additional work included repairing the station bus canopy and addressing water infiltration, predominantly at platform level.

The station entrances, mezzanines, platform, and exterior public areas including main station and bus structure, elevator structure, south auxiliary entrance and the two auxiliary Spaulding Avenue entrances were power-washed, and the non-masonry wall, ceiling and canopy surfaces repainted. Special attention was paid to remove water stains and graffiti.

Existing light fixtures were cleaned and refurbished. New surface-mounted LED light fixtures were provided in the coffered ceilings and on platform walls.

Significant efforts were made to deal with water infiltration at platform level, through the walls and ceilings. Caulk was pressure-injected into the walls and ceilings where leaks were known to exist. Existing steel pans and drains were refurbished, and several new vertical steel downspouts were installed to direct water to trackbed drains. Masonry wall expansion joints were caulked and repaired. Any exposed rebar or spalling concrete in the coffered ceilings was patched and repaired.

The station’s two elevators were completely refurbished, including flooring, exterior and interior enclosures, controls, windows, doors and ceilings, lighting and electronics.

New bus canopy roofing was provided, replacing the roofing down to the decking. The canopy, entrance and ceiling soffit were patched and painted, and the bus canopy and columns were painted.

Construction began in 2019, and was substantially complete in 2020.

The City and CTA also intend to pursue Transit-oriented development (TOD) opportunities around the station.1

As part of the improvements CTA made to Logan Square as part of its Station Renewal Program in mid-2011, the brick tunnel walls opposite the boarding platform were extensively cleaned and new, additional lighting installed to increase illumination. New directional line diagram signs were installed on each side at the north and south ends of the 8-car boarding area. The horizontal tunnel-wall variant of the signs, previously only installed at CDOT-renovated stations Downtown, were being expanded to other subway stations around the system. The improvements are seen here on September 27, 2011. (Photo by Graham Garfield)
