Red-Purple Bypass repair work begins
The CTA’s Red-Purple Bypass has improved commutes for rail customers since it was put into service in November 2021, increasing service reliability and reducing delays on the Red, Purple and Brown lines. The contractor that built the bypass, Walsh-Fluor, has begun work to repair cosmetic “spalling” that occurred earlier this year during a period of freezing and thawing that led to small cracks and loosened concrete. The spalling poses no safety risk to the structure, trains or customers.
How are the repairs done? Construction crews remove “anchor rods” – the metal elements that connect the noise barrier to the concrete bridge – one at a time and regrout them. This will make sure that no water or ice can enter them this winter. For the spalls that already exist, the workers will use lumber to create the shape of the area on the bypass exterior that needs to be fill with concrete material – similar to how a new sidewalk is poured and cured.
We have required the contractor to repair this quality issue at their expense. There will be temporary platforms mounted to the bypass to perform the repairs as they are completed in the coming months. Crews will continually monitor and remove loose materials and cordon off work areas over sidewalks and streets for everyone’s safety.
RPM temporary station wins architecture award!
On Sept. 16, 2022, the CTA proudly announced that the temporary Bryn Mawr Red Line station has received the Lerch Bates People’s Choice architectural award in the “Civic” category from the American Institute of Architects (AIA) Chicago chapter. The station, designed by EXP, an engineering and design firm, and built by contractor Walsh-Fluor Design-Build Team, was selected as the winner by the public in open voting from the finalists’ designs chosen by Chicago Architecture Center’s Docents in a round one jury review from over 125 projects submitted.
The station was built to serve rail customers during construction of the agency’s $2.1 billion Red and Purple Modernization (RPM) Phase One Project, which includes rebuilding Bryn Mawr and three other Red Line stations into fully accessible, modern facilities. Upon receiving this award, the Bryn Mawr temporary station joins an esteemed list of CTA stations that have received architecture awards and recognition, including the Garfield Green Line station, 95th/Dan Ryan Red Line, Washington/Wabash Loop, Cermak-McCormick Place Green Line and Damen Blue Line.
