Upcoming traffic shift on the 12th Avenue North and I-29 bridge deck begins Monday morning in Fargo

Starting early next week, the North Dakota Department of Transportation (NDDOT) contractors will begin the next phase of project work for the 12th Avenue North and I-29 bridge deck overlay. Crews will shift traffic head-to-head on the newly improved roadway on the north side of 12th Avenue North between Aggregate Industries Drive to Daisy Lane. The shift will allow crews to begin work on the bridge deck overlay and concrete pavement repair (CPR) on the south side.

After 6 a.m. on Monday, June 15, motorists can expect the following traffic pattern on 12th Avenue between Aggregate Industries Drive to Daisy Lane:

• Single lane in each direction will be carried head-to-head on the north side of the bridge
• Speeds will be reduced to 25 mph where traffic control is present

The bridge deck overlay is a preventative maintenance to expand the life of the bridge and improve ride quality. If left untreated, the bridge deck is susceptible to spalling, which is when the top layer of the deck concrete becomes loose. The bridge rehabilitation work is expected to be complete by October.

Project work is split into multiple phases to maintain access for thru traffic. The traffic impacts for the phase work will include:

• Phase One: Traffic will remain on their respective sides with a single inside lane closure in each direction for removal of the raised medians
• Phase Two: Traffic will be shifted to the south side of the bridge for bridge deck overlay and CPR work on the north side
• Phase Three: Traffic will be shifted head-to-head on the north side of the bridge for bridge deck overlay and CPR work on the south side
• Phase Four: Traffic will be shifted back to their respective sides with a single inside lane closure in each direction for construction of the median pavement and raised median islands
