State Route 149 Widening

Construction Updates

Motorists and residents should expect one-way flagging where active roadway widening work is underway. Please plan for extra time when travelling through the area.

Project Description

State Route 149, a rural collector that leads from US 40 to the western entrance of Dinosaur National Monument, is the main access to Dinosaur National Monument from Utah. The route begins at the junction with US 40 and terminates at the boundary with the monument at mile post (MP) 4.2. The existing paved widths vary from 22 to 26 ft. The proposed project consists of widening the existing facility to two, 12 foot lanes with two, 4 foot shoulders (32 foot paved width) and includes 17 culvert replacements and a bridge replacement at approximately MP 2.7 (Brush Creek). Subgrade stabilization is proposed from MP 3.2 to 4.

The bridge and culvert replacements are substantially complete, with crews beginning to remove and reconstruct the roadway in sections. Final paving operations are scheduled to be complete by beginning of September, 2018. More information can be found at
