Why it Matters
Bridge decks on the Lawyer’s Creek, Clearwater River and the North Fork of the Clearwater bridges were rehabilitated. The three projects were bid in one contract. The work will extend the life of the bridges, reduce maintenance costs and improve highway safety. The project is estimated to create or sustain 18 jobs. Construction started in July and was completed in August of 2010.
A liquid treatment was applied manually to the Lawyer’s Canyon and Ahsahka Bridges to seal and preserve the bridge decks. A thin layer of silica sand was added to the bridge deck to improve traction for vehicles.
The Clearwater River Bridge project includes filling and sealing of cracks on the bridge deck and the application of a porous product to help absorb and retain de-icing chemicals. The special process is expected to reduce the number of de-icer applications required on the bridge.
