The new bridge will feature two lanes with a center median, lights and sidewalks.
Two lanes of traffic will run on the recently reconstructed west half of the bridge once work begins on the east half this spring. The intersection of Fourth Street and ID-41 near the bridge is planned for closure again.
Construction is scheduled to begin Monday, April 1. One lane will remain open in each direction over the bridge. Crews will be finishing up the sidewalks and guardrail as well as finalizing the northwest retaining wall for the first few weeks.
