Bob Ortblad warns of what will happen if the Interstate Bridge Replacement Program team’s plan to politically pressure the Coast Guard to accept its Locally Preferred Alternative

Washington and Oregon are risking $2.5 billion of federal grants to replace the Columbia River I-5 Bridge. The U.S.Coast Guard has suggested the Interstate Bridge Replacement Program (IBR) consider a tunnel as an alternative to an impractical tall bridge (178-foot clearance).

The USCG must see that the IBR’s “Tunnel Concept Assessment” is incorrect and misleading. The IBR is ignoring the USCG‘s 178-foot clearance requirement and has pressed municipalities and agencies to approve its “Locally Approved Alternative” (LPA) a too low bridge (116-foot clearance).
If the IBR‘s plan to politically pressure the USCG to accept its LPA fails, federal funds will go to better projects.
The Washington-Oregon Legislative Committee should support the USCG’s tunnel evaluation recommendation and hire a consultant, independent of the IBR, to do an honest evaluation of an I-5 immersed tunnel.
