New overhead message sign alerts northbound Highway 52/Lafayette bridge drivers to congestion, delays ahead

ROSEVILLE, Minn. –Motorists traveling northbound Highway 52 onto the Lafayette bridge at the east end of downtown St. Paul will now be alerted to traffic backups and congestion ahead. A new overhead message sign, located above the northbound highway just south of Concord Street, was turned on this afternoon to alert motorists to backups and delays on the northbound highway and ramps to I-94, East 7th Street and northbound I-35E.

Sensors on the bridge will measure traffic speeds on the northbound highway.  When slow traffic is detected, the electronic sign at Concord Street will activate to warn drivers about slow traffic ahead.  The message also will provide information to direct motorists to the correct lane for their exit at the I-94 interchange.

Queue warning systems have been used extensively in Minnesota work zones but this is the first permanent application of such a system.

A study is underway to develop proposed improvements to safety and traffic flow at the interchange of Highway 52 and I-94. The study will address queuing, high crash numbers and recurring delay at the interchange. For more information, visit www.mndot.gov/metro/projects/lafayettebridge/index.html.
