Sign foundation work on SR 99/Aurora Avenue North complete (for now)

Posted on Mar 1 2016 10:41 AM
Crews have finished installing concrete foundations for new overhead traffic signs on SR 99/Aurora Avenue North. Located between the Aurora Bridge and just north of Mercer Street, these traffic signs will communicate important information to drivers approaching the future SR 99 tunnel – similar to the large signs on I-5 and other highways. 
Crews finished foundation work near Comstock Street on Tuesday morning, March 1. The project began in mid-January and required lane reductions along this section of Aurora. Thank you for your patience and flexibility as we completed this work. 
Minor electrical work continues 
Electrical crews will continue working for one to two more weeks to install underground electrical cabinets and connect communications lines to the overhead system. This work will continue to intermittently close one southbound lane at Valley Street and Raye Street during off-peak hours only.
Future lane closures on SR 99 
This spring crews will return to SR 99 to erect the metal sign structures at each of the new foundations (the actual signs will be hung at a later date). Because of the size of the structures and the equipment needed, this work will require partial or full directional closures on SR 99. We will notify the traveling public of expected traffic impacts once this work is scheduled. 
For questions or concerns about SR 99 lane closures, contact us at or 1-888-AWV-LINE (298-5463).
