Improvement project begins on Highway 385

Project Update

June 2, 2023 - Southeastern Colorado - Work is underway to replace a bridge and realign a segment of US 385 between Grenada and Bristol

Prowers County — Work is underway to replace a bridge and realign a segment of US 385 between Grenada and Bristol, near County Road FF, north of the Arkansas River.

The project consists of shifting the highway 35 feet east of its current location for 2.6 miles, providing for a smoother alignment. An 88-year-old timber bridge also is being replaced with a concrete box culvert to accommodate higher accumulations of water and lower the risk of roadway flooding.
