To pave asphalt over concrete, first we need to "crack and seat" the concrete. A cracking machine, which you can see in the video, drops a 6-ton blade onto the concrete to crack it, then a 35,000-pound rubber-wheeled roller compacts, or "seats" the cracked concrete. Then we can pave it with asphalt. | WSDOT

We are currently testing this machine to see if it’s something we want to purchase to help with litter cleanup efforts. You might have seen us out in Spokane Valley on a test run last week. The machine is towed and controlled by one person driving a tractor. It uses a rotating conveyor that contains hundreds of tines which scoops up the trash then dumps it in a hopper/bucket. The hopper can be raised to dump the litter into a container, truck or dumpster. It’s effective on grass, dirt, and paved

During the northbound I-5 Interstate Bridge closure Sept. 12-20, travelers between Vancouver and Portland will share the three existing lanes and sidewalk on the southbound bridge. A movable concrete barrier will shift lanes to allow for two lanes of travel in the direction of the heaviest commute times. For example, the bridge will have two southbound lanes and one northbound during the AM commute, and two northbound lanes and one southbound in the PM. This video shows how crews will switch the

What do we want? A guardrail worth fighting for. The SR 153 Methow River Bridge reopened this week with a repaired southbound rail! The southbound lane was closed in August for safety after an inspection determined that it may no longer stop an errant vehicle should there be a crash. Our contractor crew got down to business and worked seven days a week to install 302 feet of new railing and perform some structural and deck repairs. From there, we had to wait 10 days for the concrete to cure. And

Our maintenance and bridge teams recently took part in a hydromill demonstration in Spokane. The robotic machine is controlled by a single operator and uses up to 40,000 psi water jets to cut and demolish concrete. It negates the use of a jackhammer, saves time and significantly controls dust. We haven’t committed to purchasing any yet but we’re always looking for ways to improve the efficiency of what we do and safety of our crews and the public so we’re looking into it. | WSDOT
