Caveman Bridge Rehabilitation
Thank you Grants Pass!
We had a great turnout for the Caveman Bridge open house March 15.
We even had some special visitors who are looking forward to the rehabilitation project when it begins later this summer, after this Labor Day.

Total Projected Cost

Construction Schedule
Sept. 5, 2017- Feb. 2019
Bids: May 11, 2017
The landmark concrete ‘through arch’ Caveman Bridge opened to traffic in 1931. Designed by famed bridge builder Conde McCullough, it’s in need of repair. More than 18,600 vehicles cross the bridge daily and is rated as ‘structurally deficient’.
Problem & Scope: There is cracked, broken concrete and exposed rebar, failed joints and delamination of the bridge deck. This project will rehabilitate the nearly 550 foot long structure -  including grinding off the existing asphalt road surface and replace it with a microsilica deck. Add-on street lights from the 1960s or 70s may also be removed. Scope is still being refined by technical representatives.
Construction timing: ODOT Bridge estimates this may be a 14 month project, with total contract time of 17 months.
There will be 12 non-consecutive full night closures off the bridge.Detours will be in place.
Single lane closures at night 7 p.m. - 7 a.m. will occur regularly throughout the project.
Traffic may be held for up to 20 min. during these night time single lane closures.
