Eastern Plains Timber Bridge Replacement

About the Project:

Ten timber bridges throughout the region are in the process of being removed and replaced with concrete bridges or box culverts. Seven bridges are now complete. Roadway pavement on the bridge approaches will be removed and replaced. Outside shoulders will be widened to eight feet across each bridge or box culvert. Other project work includes new guardrail, drainage improvements, access modifications, and upgraded signage and striping. Drivers should expect full roadway closures for each of the three remaining bridge replacements.

Phase 1 bridges are now complete. More information can be found on the Eastern Plains Timber Bridges Phase 1 page.

Phase 2 work is nearing completion. All three bridges have been replaced. Finishing work, including final paving and striping, is planned this summer.
