A $102M (£78M) programme to upgrade Chicago’s metro red-line has appointed Arcadis as its principle contractor.
Acardis will led a joint venture with Jacobs and Ardmore Roderick to work with the Chicago Transit Authority (CTA) in a project to update one of the busiest lines of Chicago’s elevated metro (shortened to “L”).
The project covers 15.4km of L track that is almost a century old. The aging infrastructure needs frequent maintenance that regularly causes delays to commuters in the city.
As well as new track structure, four aging red-line stations at Lawrence, Argyle, Berwyn and Bryn Mawr, along with the existing four-track alignments will be completely rebuilt.
The JV will also construct a bypass north of the Belmont station to address significant capacity constraints caused by a 112-year-old track junction where the Brown line intersects with the Red and Purple lines.
“This project will improve rider experience, reduce overcrowding and help CTA meet rapidly growing demand for transit service in Chicago,” said Arcadis city executive in Chicago LeeAnn Tomas-Foster. “We are honoured to work with CTA to improve quality of life for Chicagoans.”
The program will be completed in phases, allowing CTA to maximize improvements while minimizing impacts on riders and the community. Construction on the first phase is set to begin in the second half of 2019 and finish in 2025.
