On-ramp to northbound I-380 from Wilson Avenue near Cedar Rapids to close Friday night #iatraffic

Posted on: June 15, 2017

CEDAR RAPIDS, Iowa – June 15, 2017 – A bridge deck overlay project on the northbound Interstate 380 bridge over 15th and 16th avenues in Cedar Rapids will impact traffic flow on I-380 and also on the on-ramp to northbound I-380 from Wilson Avenue beginning at 7 p.m. Friday, June 16, weather permitting, according to the Iowa Department of Transportation’s Cedar Rapids construction office.

All southbound I-380 traffic in the project area is shifted to the right to create an additional lane for northbound traffic.

Half of the bridge on northbound I-380 over 15th and 16th avenues will be closed at one time to complete the overlay work. On the bridge there will be two open lanes next to the work area with barrier rail in place to separate traffic from the work area.

Beginning at 7 p.m. Friday, June 16, until approximately Friday, Aug. 18, the on-ramp to northbound I-380 will be closed. During this closure, traffic will be detoured to southbound I-380 and 33rd Avenue to reach northbound I-380.

Depending on weather conditions, sometime during Friday, Saturday, or Sunday the inside lane traffic of northbound I-380 will be shifted to the newly created lane on the southbound I-380 with a crossover, and then shifted back onto northbound I-380 at another crossover after the bridge. Barrier rail will be in place to separate the traffic between the north- and southbound lanes. Truck traffic will be required to go straight on the northbound lanes and will not be allowed on the crossovers.

This project is expected to be completed by the end of October.    

The Iowa DOT reminds motorists to drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, drivers should stay alert, allow ample space between vehicles, and wear seat belts.
