I-84 Five Mile Bridge


Project Description
I-84 , Five Mile Bridge, Boise
Key No. 09493
ITD Project BR-84-1(069)48

The Idaho Transportation Department (ITD) will rehabilitate and resurface the Five Mile Bridge over Interstate 84. The project will rehabilitate the bridge deck, repair deteriorated pavement, extend the life of the structure and provide a smoother ride for motorists.

Work will be limited to the resurfacing project; no additional improvements (such as additional travel lanes, bike lanes or sidewalks) are planned as part of this project. Improvements of that magnitude would require total replacement of the bridge structure, and funding for such an extensive project is not currently available.

Project Background
The Five Mile Bridge, built in 1966, carries more than 18,000 vehicles a day. By 2031, average daily traffic is projected to exceed 19,250. The bridge is part of a heavily-traveled north-south corridor in west Boise, adjacent to residential, retail and business centers, making it an important transportation link in the area.

Proposed Construction Schedule
For the following reasons, ITD is recommending an expedited construction scheduled that would include the temporary closure of the bridge:
  • Construction is cut from 40 days to 25 days, allowing the project to be completed two weeks earlier than if the bridge remains open.
  • The "get in, get out" repairs mean a full flow of traffic is restored sooner.
  • The finished roadway surface is constructed in one efficient process.
  • A cost savings is expected. (If the bridge is closed standard construction costs, such as traffic control measures and temporary traffic signals, and the need for flaggers, are automatically eliminated.)
What do you think?
Are there other issues that ITD should consider in determining whether to close the bridge during construction?

ITD is interested in hearing from residents, businesses and commuters about which option is preferred.
