Orange Line Haymarket North Signal Replacement Project

The Orange Line Haymarket North Signal Replacement project awarded to the joint venture of J.F. White Contracting Co. and SYSTRA Consulting Inc. will replace the Authority's existing Orange Line signal system with a fully functional state-of-the-art signal system from Chinatown to Oak Grove. Included as part of this project is the installation of new Switch Machines, Train Stop devices, Track Circuits, Signal Rooms and cabling throughout the project limits. The installation of this new system will significantly improve system reliability and throughput while at the same time allowing for increased operational flexibility.

It is anticipated that this project will commence on March 28, 2004, the duration of which, is projected to take four (4) years to completely install and test.

The joint venture of J.F. White Contracting Co. and SYSTRA Consulting Inc. will be allowed to early access the right of way from 9:00pm to 5:00am, Sunday through Friday, for three (3) consecutive construction seasons as follows.
