Project Role and Scope of Work

The length of the project was 24.1 miles or approximately half the length of the Expressway. The work under the widening project included bridge widenings, box culvert extensions, installation of overhead sign structures, and installation of highway lighting at interchanges. Additionally, various Intelligent Transportation System (ITS) components were incorporated along the Expressway, including Closed Circuit Television (CCTV) Cameras, EZ-Pass Tag Readers, and Overhead Dynamic Message signs.
