What happened the last time a new transportation corridor was built? That’s a question everyone should ask, now that our legislature is considering rebuilding the I-5 Interstate Bridge.

It took a decade to exceed 1982 I-5 vehicle counts. Now that’s congestion relief!

Portland has the nation’s 12th worst traffic congestion due to a lack of investment in roads and building new transportation corridors. Exacerbating the problem are more trucks on the I-5 corridor. The Port of Portland lost marine shipping capacity caused by shipper Hanjin’s recent departure, putting more trucks on I-5 to Tacoma and Seattle.

This will provide relief from everyone presently forced through the three-lane Vista Ridge Tunnel in downtown Portland.
