Get ready for Gorge road construction


News staff writer

While project start dates are off in the future, from 2007 to 2011 there will be almost constant bridge construction on Interstate 84 from the The Dalles to the Sandy River.

Planners, engineers and project managers with the Oregon Department of Transportation held the first open house explaining the projects Oct. 25 in The Dalles.

The event focused on the first phase of work, which involves both bridge replacement and repair between The Dalles and Hood River.

Repairs will be made to the Rock Creek Bridge in Mosier and the Hostetler Way Connector Bridge, which are being done on a separate schedule.

“We wanted to get those repairs going as quickly as possible,” said John MacArthur, the program manager with Oregon Bridge Delivery Partners.

Part of the team’s concern is due to cracks in concrete on those structures. That has resulted in reduced load carrying capacity for the bridges.

“It’s not safe,” said Terry Stones, of David Evans and Associates, the design firm for the project. “The work will bring those bridges up to the level required for all continuous use permits (for trucks).”

Aside from the higher cost of $33.9 million, plans to replace a bridge over Mosier Creek and at Fifteen Mile Creek will have something the repairs won’t as plans include seismic readiness for the new structures. Retrofitting for earthquakes won’t be done on the two repair bridges in the segment because of not enough project funding.

However, the rest of the entire list of projects is fully funded through monies from both the Oregon Transportation Investment Act (OTIA) and the Statewide Transportation Improvement Project (STIP).

Repair work involves strengthening cap beams, girders and crossbeams. The design is expected to be approved in Dec. 2006, going out to bid in April 2007 with repair work slated for spring to fall of 2007.

A new element marks the projects’ design as ODOT installs the first Gorge standard barriers replacing the current median. MacArthur worked on a team that developed the Interstate Corridor Strategy.

“It is the idea of continuity,” he said. “The document is a true stakeholder vision of what they want the Gorge to look like in 30 years.”

Copies of the I-84 Corridor Strategy are available online as a pdf file or to study at the Gorge Commission office in White Salmon.

The other phases of bridge repair are slated for three distinct geographic regions, which include:

* From Cascade Locks to Hood River, replacement of three bridges and repair of eight bridges. The final design is due early 2008 with construction set for 2008 to 2010.

* From Dodson to Tanner Creek, replacement of one bridge and repair of three bridges. The final design is due Nov. 2007 with construction from April 2009 to 2011.

* Bridges over the Sandy River and at Jordan Road, replacement of two bridges, repair of two bridges. The final design is due Nov. 2007 with construction from March 2008 to Dec. 2010.
