Snake River Bridge at WY 22 Project
About this project
The Wyoming Department of Transportation (WYDOT) is making improvements to Wyoming State Highway 22 (WY 22) between Jackson and Wilson in Teton County. The existing Snake River Bridge will be replaced with a four-lane bridge with a new pedestrian underpass west of the river. Because the WY 22/390 intersection is located very close to the bridge, it will be reconfigured to improve traffic flow. To improve safety, the project also includes installation of four wildlife crossings, as well as wildlife fencing, wildlife jump outs, and cattle guards.

Construction update information
The project will start with installation of a new pedestrian underpass and minor work on the Jackson Hole Community Pathway, followed by reconstruction of the bridge.
The informal parking area southwest of the bridge, which has been utilized as a parking area for those wishing to access the levy area, is closed. A new pedestrian access from the boat ramp and under the new bridge to the levy will be available upon work completion.

Thursday, Dec. 5, 7 p.m. to 11 p.m.
Evening work, lane closures, scheduled for Snake River Bridge
WYDOT and contract crews from Ames Construction will be placing some new, temporary lane markings at the intersection on Thursday, Dec. 5, from 7 p.m. to 11 p.m. The work will require lane closures controlled by flaggers. Drivers will see one-way traffic while the work is underway and should expect delays in the evening from 7 p.m. to 11 p.m. The work is scheduled for one night.
Drivers are advised to be extra cautious of roadside workers and expect delays in the evening.
Unforeseen circumstances may necessitate adjustments to the schedule. WYDOT remains committed to keeping the public informed and prioritizes the safety of all travelers and construction crews. Please reduce speed while traveling through the construction zone and pay close attention to adjusted traffic patterns, signage, and flaggers’ instructions.
To receive alerts on this and other road conditions and closures, drivers can sign up for 511 Alerts.
Crews have finished the final lift of pavement through the intersection and WYDOT traffic crews will be striping those newly paved areas beginning the night of Tuesday, October 15th. Crews will be striping from 10 p.m. to 6 a.m. The work is scheduled for one night. 
WYDOT will be working on the final paving work of the season on Wyoming State Highway 22 and Wyoming State Highway 390 starting next week. Beginning Monday, October 7, weather permitting, WYDOT, with crews from Ames Construction, Inc. and Evans Construction, will place a final layer of asphalt in construction areas along WYO 22 and WYO 390. Additionally, crews will pave the turn and approach from WYO 22 to Emily Stevens Park Road. What drivers can expect during construction
WYDOT will replace the bridge and roadway approaches in phases so traffic can be maintained during construction. While the south half of the new bridge is under construction, traffic will be maintained on the existing bridge. When that first phase is complete, traffic will be moved to the two travel lanes on the south half of the new bridge. The old bridge will be removed to make room for the construction of the north half of the new bridge. When the north half is complete, all four lanes of traffic will be open. No detours are anticipated, and vehicular traffic will be maintained throughout construction.
What pathway users can expect during construction
WYDOT will strive to keep the pathway open during construction; however, short-term closures may be needed to maintain safety.
