Westwood Curtis Construction excavated and installed a 101-foot precast concrete tunnel beneath Highway 22 to safely route pathway traffic across one of Wyoming’s busiest transportation corridors. The project was completed during peak tourist season while maintaining two-way traffic throughout construction.

Project highlights include:

• Excavation and installation of a 101-foot precast concrete pathway tunnel

• Construction beneath Highway 22, the busiest non-interstate highway in Wyoming

• Work performed during peak tourist season with continuous two-way traffic maintained

• Coordination of mass excavation operations in a constrained roadway environment

• Installation of storm drainage and dry utilities as part of the tunnel infrastructure

• Careful traffic control and sequencing to minimize congestion and disruption

This project demonstrates Westwood Curtis’s ability to execute complex underground infrastructure work in high-traffic conditions while maintaining safety, access, and schedule integrity.

Westwood Curtis Construction excavated and installed a 980-foot tunnel beneath Snow King Mountain Resort to provide access to a newly developed subdivision in Jackson, Wyoming. Due to an accelerated design timeline, Westwood Curtis was engaged early in the process to provide value engineering and construction planning support.

Project highlights include:

• Excavation and installation of a 980-foot tunnel beneath Snow King Mountain Resort

• Early involvement in value engineering to determine construction methods and feasibility

• Coordination on precast tunnel dimensions, sequencing, and scheduling

• Excavation reaching depths of up to 80 feet below existing grade

• Execution under complex geotechnical and access conditions

• Commendation from OSHA inspectors for safety procedures and compliance

This project demonstrates Westwood Curtis’s capability to manage deep, technically complex tunnel construction while maintaining high safety standards and schedule coordination.

Beginning in 2010, Westwood Curtis Construction constructed a pedestrian underpass in Jackson, Wyoming to provide safe access to the Hidden Ranch residential area. The project required demolition of an existing underpass and retaining walls, all within a narrow roadway and highly constrained work zone.

Project highlights include:

• Removal of an existing pedestrian underpass and retaining walls

• Construction within a restricted work zone and narrow roadway

• Installation of steel pilings in drilled shafts

• Construction of timber retaining walls

• Grading, subdrain installation, and paving

• Relocation of underground utilities

This project reflects Westwood Curtis’s ability to deliver precise underground and pedestrian infrastructure work in constrained urban environments while maintaining access and safety.
