(Salem, OR) -- Two Republican lawmakers want the Oregon Department of Transportation to study a third bridge over the Columbia River, west of I-5. Dundee Senator Bruce Starr and Tillamook Senator Suzanne Weber introduced a bill for a feasibility study, which would also look at whether another bridge would alleviate congestion in the Portland area. The Interstate Bridge Project group reviewed the idea, but didn't pursue it because it doesn't resolve seismic problems with the I-5 bridge and relieve traffic problems with that crossing.
