  • Phase 1: Install traffic control on 6th Street moving westbound traffic to eastbound lanes to allow for construction of the westbound lanes. Install traffic control on I29 switching northbound traffic to southbound lanes and vice versa for structure removal and construction of Phase 1 Bridge. Removal and reconstruction of northbound on-ramp and southbound off-ramp at I-29 Exit 132. Closure of 22nd Avenue intersection (May 8 - August 11 tentatively) to allow for intersection reconstruction and utility installations.
  • Phase 2: Install traffic control on 6th Street moving traffic to newly constructed westbound lanes and Phase 1 Bridge to allow for the construction of eastbound lanes, removal of existing eastbound Bridge and complete Phase 2 Bridge. Removal and reconstruction of southbound on-ramp and northbound off-ramp at I29 Exit 132
  • Phase 3: Complete proposed median pavement, curb and gutter, sidewalks and service roads that were not completed during phases 1 and 2.

Traffic Affects:

22nd Avenue Closure Detour - effective May 30 for 75 days

Through traffic and over-width traffic will be detoured to I-29 and the U.S. 14 bypass. Local traffic will be detoured onto State Avenue and Sunrise Ridge Road from the south and 9th Street and Sunrise Ridge Road from the north. No Parking will be allowed along the detour routes for the duration of the closures and will be signed accordingly.

Two-way traffic will be maintained on the remainder of 6th Street during construction with one half of the roadway constructed at a time. Drivers needing to access the industrial park area are encouraged to use the U.S. 14 bypass and 34th Avenue. Please allow extra time for travel if utilizing these routes.

There will be a number of speed reductions including, 45 mph on the Highway 14 bypass along the detour route; a 30 mph speed reduction for 6th Street through the project limits and I-29 traffic speed will be reduced to 65 mph through the bridge construction limits just north and south of Exit 132.

The contractor will be installing "Business Signs" along the local detour routes to help direct the local traffic to access points for the affected businesses.
