Project Facts
- Construction began March 13th and was complete April 28th, avoiding the Memorial Day traffic.
- A detour was required for about 2 months to safely repair the narrow (26 foot wide) bridge deck.
- A deck overlay does what just patching could not, preserving the life of the structure.
This project was completed April 28th, 2006.
This Structure Preservation Program Project rehabilitated the deteriorating bridge deck on the SR 283 Winchester Wasteway Bridge in Grant County.
Why is WSDOT
rehabilitate this bridge deck?
The bridge was constructed in 1953. The deck was experiencing cracking and spalling concrete, and exposed reinforcing steel. In March 2004, testing showed approx. 41% of the deck area experiencing deterioration, with 2% being the threshold to consider repair and/or overlay. Deck repair and overlay were required to preserve the deck.
The End Result
The deck repair will removed approximatley 1/2" of deteriorating concrete, and added a 1-1/2" deep concrete overlay to provide a smoother, safer ride.
Project Benefits
- Preserves bridge life while minimizing ongoing repair costs
- Reduces likelihood deck replacement will be required in the future
- Replaced current cracked, patched, spalling surface with new smooth surface
- Provides additional cover over reinforcing steel to decrease surface cracking
- Improves structural integrity
What is the project timeline?
Construction began April 4th and was complete on April 28th, 2006.

Services Web site for more information.
Increasing safety is one of our priorities
Besides the safety benefits of the project itself, safety for the public and the construction workers is paramount while the work is underway. A comprehensive traffic control plan and a work zone safety plan was prepared to protect travelers and workers. The narrow structure required a detour to reroute traffic to allow the project to be completed safely and efficiently.
Will this project impact tribal resources?
Following consultation with the Colville Tribes, no impacts were identified. WSDOT addresses the concerns of tribal nations using the process outlined in Section 106 of the National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOT Centennial Accord Plan.
