SR 410 is one of only East/West Crossings in Washington. Due to snow, it is open 6-7 months a year. To minimize the impact to the community and traveling public, the Federal Highway administration required that the project be accelerated. Conway Construction worked 6 days a week to remove asphalt as thick is 4′, perform roadway excavation, build 2,800 square feet of mechanically stabilized earth (MSE) walls, replace culverts, place base rock and pave. Conway Construction met the aggressive project schedule and earned the commendation of both the National Parks Service and the Highway Administration
