MOSES LAKE — Work on the Hansen Road overpass over Interstate 90 gets back into full swing Monday, and drivers can expect traffic revisions from Monday through Friday while crews install the bridge girders. 

Summer Derrey, public information officer for the Washington Department of Transportation North Central region, said completion is now scheduled for mid-February. Some work on the project was suspended while DOT officials worked to address some concerns with the girder manufacturing process. 

"It was a bad batch of concrete, basically," she said.  

Production was suspended while additional quality-control measures were instituted, she said.  

"It was resolved and they're starting work on Monday," she said.  

Installation of the girders will mean traffic will be diverted away from sections of the freeway while the work is underway.  

"Eastbound traffic will be reduced to a single lane along I-90 and will be shifted to westbound lanes via a median crossover at Hansen Road," Derrey wrote in a WSDOT press release. "Due to this traffic revision, exit 174 will be closed to eastbound traffic." 

Exit 174 provides access to the neighborhoods south of I-90. Drivers heading east who want to get to the areas south of I-90 will have to use the exit at Hiawatha Road and then use South Frontage Road. Eastbound drivers who want to get to Mae Valley can use the Hiawatha Road exit and North Frontage Road. 

"Westbound I-90 travelers will be detoured via the off- and on- ramps at exit 174 to continue onto westbound I-90," Derrey said. 

Westbound drivers who are going to Mae Valley are asked to use the Blue Heron Park exit, which is exit 175. Drivers heading west who want to get to areas south of I-90 will be detoured to Hiawatha Road. 

Once the installation is completed and the freeway reopened, traffic will be restricted to one lane in each direction throughout the rest of the project, Derrey said. Signs guide travelers through the construction zone.
