HCRH Guardrail Replacement
The Oregon Department of Transportation will be replacing seven sections of guardrail on the Historic Columbia River Highway between the Troutdale Bridge and Dabney State Park (mileposts 0.5 to 4.6). The new guardrail will match the historic white double-rail type found on many other sections of the Historic Highway.
Why is ODOT building this project?
The current guardrail has reached the end of its useful life and needs to be replaced.
The new guardrail will provide enhanced safety for motorists and be more consistent with guardrail in other sections of the Historic Highway in the Columbia Gorge National Scenic Area.
Impacts to the Local Area
Traffic: There will be single lane closures at each location as the new section is installed. Flaggers will direct traffic and delays will be limited to less than 5-minutes. Work will start on the first section near the Troutdale Bridge and move eastward.
Noise: All work will occur during the daytime. There will be minimal noise at each location during the post driving, excavation and paving phases.
Work on the project will start in early May and be done by mid-July. The contractor will work Monday through Thursday from 7 a.m. to 5 p.m.
The construction costs for the project are $692,830 and the funding comes from two sources. 80% is funded by the Federal Scenic Byways program and 20% comes from state funds.
