Senator Patty Murray, from Washington State, announced that the Interstate Bridge Replacement (IBR) Program – the organization tasked with replacing the I-5 Bridge connecting Portland and Southwest Washington – will receive $600 million in federal funds from a US Department of Transportation (DOT) grant program. The bridge, which spans the Columbia River, connects Washington and Oregon via I-5.
The Oregon and Washington DOTs are leading the replacement effort, which will see:
- Construction of a new Interstate bridge that will be high enough so that bridge lifts are not necessary and that meets current seismic standards.
- The inclusion of a dedicated, high-capacity guideway for services such as light rail; safety shoulders and ramp-to-ramp connections (auxiliary lanes) to improve the flow of traffic and safety; and a shared-use path at least 10 feet wide.
- The replacement of the North Portland Harbor bridge, which connects North Portland to Hayden Island on I-5, to meet seismic standards.
Project officials said they could receive as much as $2.5 billion of total federal funding.
