Jul. 9—After more than three years of construction, a new bridge crossing the Spokane River on Trent Avenue will open to traffic this week.

The opening is happening sooner than expected. With 880 working days permitted for the bridge, the construction team completed the project in 578.

Garco Construction helped in shortening the timeline for the new bridge. The contractor decided to use rock paths in the river, giving workers better access when removing the old bridge.

The previous Trent bridge stood for 110 years, and was determined to be structurally unsafe.

"The concrete was failing. It was structurally deficient and did not meet today's current engineering standards," said Ryan Overton, Washington State Department of Transportation spokesman. "It had reached the end of its life cycle and had significantly outlived its life cycle."

Although none of the old bridge was saved during reconstruction, there were a few design aspects used from the old design.

"It is a completely new bridge, but a lot of the style was kept intact," Overton said.

The outside barrier and concrete stampings were replaced but kept the same design, along with the same arching cutouts on the pedestrian railings.

The new bridge is 520 feet long and 50 feet wide, said Jody Qualley, Washington State Department of Transportation transportation engineer. The bridge includes 5-foot-wide shoulders to serve as bike paths, a 10-foot-wide walkway on the south side and a 6-foot-wide walkway on the north side. It also has one lane for each direction.

Due to water levels, "we would only work in certain windows of the year," Overton said.

Despite the project taking multiple years to be completed, the process went smoothly, transportation officials said.

"We were worried about some risks, but they did not become a problem for us," Qualley said.

The project cost $25 million, about a $1 million less than expected.

The ribbon cutting will occur Monday at 10 a.m., and traffic will open either Monday evening or Tuesday morning.

The Washington State Department of Transportation has high hopes the new Trent Bridge will last just as long as the last one.

Larry Reiner, assistant manager at Spokane Power Tool & Equipment located west of the bridge, is relieved the bridge will soon reconnect Trent Avenue.

"We have to send people west to go east. Our customers have been asking us for a long time now, 'Hey when is that gonna open?' and we're glad they got it done before their deadline," Reiner said. "It's going to help business tremendously."
