Work on a new State Avenue bridge, seen here on Aug. 11, has continued throughout the summer.

 

Marysville’s State Avenue bridge construction passed some major milestones recently as work on the project continues.

The project from 100th Street to 104th Place is one of the last areas of State Avenue that is constrained to three lanes and has been an occasional bottleneck for Marysville traffic.

“We are widening the existing lanes in the corridor,” said Pat Gruenhagen, senior project engineer.

It will be increased to five lanes when the project is completed.

“That will make it consistent with what we have to the south,” he said.

The work completed some big parts of the project recently, including the pile driving for the bridge.

“The pile is being put more than 100 feet in the ground to build what will be the foundation of the bridge,” said Gruenhagen.

A crane was brought in on Aug. 7 to 9.

“This last Monday we put in a set of girders, which is what we build the bridge deck on that the cars will drive on top of,” said Gruenhagen.

The work created more traffic impact during the time, although not as much as predicted.

“We had anticipated that we would have to dismantle the crane on Tuesday, but we were actually able to finish that work on Monday,” said Gruenhagen.

The contract for the project requires efforts to reduce traffic impacts caused by the work.

“We’ve taken a phased approach to minimize our impact on the traffic,” said Gruenhagen.

He said there weren’t too many significant traffic impacts left due to the project, although northbound traffic will have to be re-routed for at least one day. That is likely to occur in the first couple of weeks of September, he said.

The bridge construction project began in March of 2020 and is expected to be completed by the end of the year.

It is funded by a $5 million grant and is currently on budget, said Gruenhagen.

In addition to a bridge, construction will add roadway lighting, as well as sidewalks on both sides of the street for better pedestrian access, and a new traffic signal at 100th Street.

Utility lines will also be moved underground.

“We have been able to team with private utilities, such as Comcast, to move the utilities lines there underground,” said Gruenhagen.

“That will really improve the cosmetics of the area,” he said.

The current road is also built on top of a culvert, which are often detrimental to fish habitats.

“There will be some creek restoration work as well in removing a culvert that the Quil Ceda Creek currently moves through,” said Gruenhagen. “That will open up the creek channel considerably so that it should improve the fish passage."

The culvert removal may need to be finished next summer depending on the timeline of the work, he said.
