CURRENT STATUS
Lanes are head-to-head on the 12th Ave N bridge over the railroad tracks. Speeds are reduced to 25 MPH.

SCOPE
In 2008, a two-year bridge project will get underway on 12th Ave. N over the railroad tracks. The entire driving surface on the bridge will be replaced and the bridge will be widened to accommodate four traffic lanes and a pedestrian crossing. Approximately half of the concrete beams will be replaced and the steel beams will be repainted. The first year will include widening the structure and completing about half of the driving surface. The remainder of the driving surface will be replaced in 2009.

The roadway work between I-29 and 10th St. will be completed in 2009. The 12th Ave. N roadway will be reconstructed from I-29 to the railroad bridge and from the railroad bridge to 10th St. The work includes extending the four lane section across the bridge to 18th St.

PURPOSE
The 12th Ave. N bridge over the railroad tracks is currently listed as “structurally deficient”, and this project will remove this bridge from that category. The 2009 roadway project will improve driving conditions on 12th Ave. N, as well as provide greater capacity with the addition of lanes.

FUNDING
The 2008 bridge project is about $11.8 million with $9.4 million federal funds, $1.2 million state funds and $1.2 million local funds. The contractor is Industrial Builders from West Fargo. The estimated cost for the 2009 roadway project is $10.8 million. Approximate split for the roadway project is 72% federal, 9% state, and 19% local.

START
For the bridge project, work that impacts traffic will begin on or after March 24, 2008. Work on the roadway project will begin in April or May 2009.
