A private contractor, M.A. Degertstrom, out of Spokane, Wash., will be demolishing the
Troy/Wegner Bridge located on the WSU Pullman campus in accordance with the timeline below. You may view the
Traffic Control Pedestrian Detour Plan or the
Logistics Narrative in PDF form, too.
Stage 1A (June 13 – June 24, 2022):
Road Closures: Stadium Way closed completely at the bridge demolition location to both directions of traffic. Access maintained to College Way and access road near south bridge abutment.
Logistics/Sequence: Equipment will be staged in the closed section of Stadium Way. Temporary chain link fence will be used to define closed areas with wayfinding signage on or in front of the fence. This stage of the project removes the 90 foot span over Stadium Way in its entirety, allowing Stadium Way to be used for the remainder of the project.
Stage 1B (June 27 – July 1, 2022):
Road Closures: Intermittent closures of the access road adjacent to the south bridge abutment, EMS and utilities will be accommodated. Stadium Way and College Way remain open, with the exception of intermittent single lane closures on Stadium Way to accommodate the adjacent Bent 1 removal and light standard removal and replacement.
Logistics/Sequence: Equipment will be staged in the adjacent access road and potentially south of Wegner Hall as needed to
accommodate traffic. Some full closures may be needed for safety, details to be worked out onsite. Temporary chain link fence with wayfinding will be used to define closed active demolition areas. Demolition will commence with the southern
span. Once that span is removed completely, Bent 1 adjacent to Stadium Way can be removed to 2 feet below grade. Work will then commence on the South abutment removal. Removed areas will be graded smooth and safety fence placed around
them until final restoration.
Stage 2 (July 5 -July 22, 2022):
Road Closures: College Way will be closed for this 3 week period to allow span removal and staging for the work north of Stadium Way. Stadium Way remains open except intermittent single lane closures for Bent 2 removal and adjacent light
standard removal and replacement.
Logistics/Sequence: Equipment will be staged on College Way, with some final staging adjacent to Troy Hall for final section of North abutment removal. Removal will proceed northward with removal of the Stair span, removal of the span over College Way, then removal of the short span north of College Way. Bent removal will follow with Bents 2 and 3 removed to 2 feet below ground. The North abutment will then be removed as much as possible with some areas remaining below ground to avoid tree damage or removal. Temporary chain link fence with wayfinding will be used to define active demolition areas. During North abutment removal, the sidewalk access to the southeast and east of Troy Hall will be blocked of with chain link and wayfinding.
Stage 3 (July 25 – July 29):
Final restoration and cleanup. Not shown on plans, restoration of hardscape and landscape areas. No traffic or lane closures anticipated except possible single lane closures. Not designed yet so full scope at this time unknown. Temporary movement of pedestrians and wayfinding will be included in this work.
