It is quite evident that planners for the Interstate 205 Glenn Jackson Bridge planned on future manufacturing, which would require sufficient clearance. Where were the planners for the Columbia River Crossing? Did we waste money on the Jackson bridge? Wikipedia describes the I-205 bridge as “a twin structure with four lanes in each direction and a 9-foot (2.7 m) wide bicycle and pedestrian path in between. The bridge is 7,460 ft (2,270 m) long from the Washington side of the river to Government Island and another 3,120 ft (951 m) in length from Government Island to the Oregon side of the river. The main span, near the Washington side, is 600 ft (183 m) long with 144 ft (44 m) of vertical clearance at low river levels. As of 2008, the average daily traffic was 134,800 vehicles.”
I personally believe we are wasting money on the present CRC height limitation for the Interstate 5 Bridge. Correct it while we can if the bridge is to be built.
