USA: Chicago Transit Authority approved a $13m contract for the Green Line West Track Renewal Project on December 9. Lowest bidder Kiewit Infrastructure Co has been selected to replace the track between Laramie and Harlem/Lake stations at the western end of the CTA’s Green Line.
Work on the 4 km section will cover replacement of sleepers, baseplates and fasteners, as well as transposition of running rails at some curves, ballast replacement and surfacing work. CTA says that the last major track renewal on this section took place in the 1980s, and 75% of the sleepers are now approaching or have already exceeded their useful life.
‘Modernising CTA’s infrastructure is a critical part of having a world-class transit system’, said CTA President Dorval R Carter Jr. ‘This investment will allow us to continue to provide affordable, reliable service to the city’s West Side, where Green Line stations on the Lake branch had more than 9 million riders last year.’
Renewal work is due to begin in March and will take place during nights and at weekends.
