ADOT installing new traffic message signs on north valley freeways

6/17/2015

NORTH VALLEY – New overhead traffic signs and other traffic-management technology will be added to north valley freeways over the course of the summer.

This Freeway Management System already is in place along much of the Phoenix-area freeway system and is now being expanded along I-17 north of Loop 101 and on Loop 303 west of I-17 to 51st Ave.

I-17 drivers can expect mostly-overnight restrictions this summer while ADOT installs the new traffic-management technology. Overhead message signs are being added along the freeway between Loop 101 and Anthem Way.

Much of the work so far has taken place along the shoulders of I-17. Crews have worked to install sign foundations and other components of the system that will allow ADOT to track traffic flow and provide the information to the public via the agency’s 5-1-1 travel information system, which is based at the ADOT Traffic Operations Center in Phoenix.

The $4.8 million project started last September and is scheduled for completion by fall 2015. In all, crews will install seven new overhead message signs above I-17, along with 15 new digital traffic cameras to help track conditions along the freeway. Pavement sensors that provide data about the flow of freeway traffic are being installed.

Drivers also will continue to notice crews doing installation work on weekdays during daytime hours, 6 a.m.-5 p.m., along the freeway shoulders and ramps in the area. Work requiring lane restrictions will for the most part be scheduled at night or weekend mornings. ADOT is urging motorists to stay alert to vehicles and workers alongside the freeways.
