Stage 1The new lanes and bridge for the southbound 24th Street traffic will be constructed. Traffic will be restricted to one lane in each direction (with left-turn lanes) and will shift to the existing northbound lanes. | |||||||
Project description
Reconstruction of the 24th Street bridge over Interstates 29 and 80 is the first construction project of the CBIS improvements project. This project involves:- Reconstructing the bridge to make it longer in preparation for full reconstruction of the I-29/I-80 overlap section in segment 2. The longer bridge will allow future I-29/I-80 lanes to pass underneath.
- Reconstructing 24th Street from just south of 27th Avenue to the I-29/I-80 eastbound ramp intersection. Upon completion, 24th Street will include two through lanes in each direction and accommodation for left-turn lanes at the interstate on-ramps.
For more information on the other CBIS improvements, see the Design page.
Construction staging
Reconstruction of the 24th Street bridge will occur in four stages. Click on a stage below for a brief explanation.Preparation stage
This is the initial construction preparation, including strengthening ramp shoulders and adding temporary pavement along 24th Street, and at ramp intersections to provide for shifting traffic in subsequent stages. In addition, new pavement will be constructed to shift I-29/I-80 westbound traffic toward the median to accommodate the new pier for the 24th Street bridge.
Stage 1
The new lanes and bridge for the southbound 24th Street traffic will be constructed. Traffic will be restricted to one lane in each direction (with left-turn lanes) and will shift to the existing northbound lanes.
Stage 2
The new lanes and bridge for the northbound 24th Street traffic will be constructed. Traffic will be restricted to one lane in each direction (with left-turn lanes) and will shift to the new southbound lanes.
Stage 3
The 24th Street bridge's median section will be constructed. Traffic will be restricted to one lane in each direction (with left-turn lanes).
