CTA selects contractor for Purple Line viaduct projects
Written by jrood
The Chicago Transit Board selected a contractor to replace three aging viaducts along the line at Greenleaf, Dempster and Grove Streets in Evanston. The project involves replacing the concrete viaducts with new steel structures, as well as new abutments, retaining walls, foundations and new waterproofing and drainage systems. The project also includes rail tie replacement, new landscaping and lighting enhancements under the bridges. "Repairing the viaducts will allow us to remove the slow zones and speed travel for customers. The new structures also will provide a safer and more attractive environment for the community," said CTA President Forrest Claypool. Kiewit Infrastructure was selected as the contractor for the $10.3 million contract through a competitive bidding process. Funding for the project is provided by an Illinois Department of Transportation grant through the Regional Transportation Authority.
