Bridges and Tunnels

Triangle Truss Pedestrian Bridge

The Triangle Truss Bridge project was the improvements of one of the pedestrian bridges in River Front Park in Spokane, WA. The improvements consisted of approximately 3440 square feet of bridge deck replacement with Ekki Wood and other related miscellaneous items. 

Strong Creek Bridge

The Strong Creek Bridge Replacement project was the replacement of the Strong Creek Bridge on HWY-200B in East Hope, ID. The existing bridge required demolition  over a protected waterway. Precast voided slabs were placed between two cast-in-place abutments. The project shutdown the main street in the city of Hope, so alternate routes including a foot bridge had to be temporarily constructed. 

Old Potlatch Bridge

The Gold Creek Bridge on SH-6 just outside of Potlatch, ID, utilized voided precast girders in conjunction with UHPC locking keyways to provide a efficient and economical product in a short time frame. Liaison between Scarsella and subcontractors required exceptional organization and communication methods to ensure the bridge could be constructed in a 12 week window

WSU Tunnel 2018

The WSU College Avenue Steam Tunnel Lid Repair included the removal and replacement of a concrete utility tunnel lid structure at multiple locations on the Pullman Campus of WSU.

Rock Creek Bridge Repair

The Rock Creek Bridge Repair project was a bridge repair on a utilitarian concrete girder bridge that was originally built in 1965 spanning the Palouse River near Potlatch, ID, that was closed in January 2017.  The timber piles that supported the concrete piers were rotting away and needed replacement.  Construction involved temporary shoring of the bridge, replacing seven of the existing piles with new steel piles and seven of the existing wood piles to be wrapped in fiberglass.
