The Bridger-Teton National Forest is making progress on replacement of 3 bridges in the Pinedale area. The Tosi bridge replacement is expected to be complete in mid-September, and the Union Pass road is now open to through vehicular traffic between Dubois, Wyoming and Pinedale, Wyoming. Crews are scheduled to begin work on the Sweeney and Half Moon bridges on the Half Moon Lake road in early September.
Hazardous conditions associated with construction of the new bridge abutments on the Tosi bridge forced a closure of the Union Pass road to through vehicular traffic starting July 31st. Though the road is now open, travelers can expect to experience short intermittent closures of up to 2 hours at the Tosi bridge. Longer delays will occur when crews are setting the new bridge deck with a crane and building the roadway approaches. The existing bridge will be used for travel until the new bridge is finalized. Travelers are urged to use caution as they proceed through the construction zone, both for their safety and for the safety of the construction workers.
Construction crews are now scheduled to mobilize to the Half Moon Lake road for the replacement of the Sweeney and Half Moon bridges. Both the Project Manager and Pinedale Ranger District personnel have been in contact with local land owners in the area, with the goal of mitigating access impacts. The Half Moon Lake road is currently scheduled to close for approximately 2-3 hours on September 5th to unload and pre-stage the bridge components. The Half Moon Lake road below the campground will then be closed beginning September 9th, when the contractor will begin excavation at the Sweeney bridge site. Once the new Sweeney bridge is constructed, the contractor is scheduled to mobilize to the Half Moon bridge site on September 16th. As part of the mobilization to the Half Moon bridge site the Half Moon Lake road will be closed at the junction with Skyline Drive. No access will be permitted through the construction sites to ensure the safety of the workers and the public. Full closure of the Half Moon Lake road is scheduled to end by September 27th.
The Pinedale Ranger District would like to extend their thanks for everyone’s patience and cooperation during these projects. Please direct any questions about these closures and bridge construction projects to the Pinedale Ranger District at 307-367-4326.
