Status

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
