Project background

The lock and the dam were officially opened in 1910, and a bridge deck and approach spans were added to the dam structure in 1913. The additions allowed motorists and pedestrians to cross the Red River in Lockport. The bridge deck has undergone major reconstruction work twice since that time, first in 1951 and again in 1993.

In 2017, it was determined that the bridge deck on the main span of the bridge was reaching the end of its service life and needed to be replaced. Inspections and studies also recommended that the underlying steel structure be strengthened and that portions of the approach spans be repaired and replaced.

The bridge deck replacement project presented an opportunity to make the bridge safer, more accessible and more comfortable for users. The final design included:
