Project Description

The Columbia River Crossing project is studying a replacement I-5 bridge over
the Columbia River with light rail extending to Clark College. In July 2008,
this alternative was selected by local project partners as providing the
best opportunities to relieve congestion, improve safety and freight mobility and increase travel
options on I-5 while meeting community needs. CRC is a bridge, transit and
highway improvement project for five miles of I-5 from
State Route 500 in
Vancouver, Washington, to approximately Columbia Boulevard in Portland, Oregon.
Purpose and Need
To address the transportation problems on I-5, a mix of bridge, public
transit and highway solutions are needed. If we do not move forward with a
comprehensive long-term solution now, the problems will only get worse. This
project will address:
- Growing travel demand and congestion
- Impaired freight movement
- Limited public transportation operation, connectivity and reliability
- Safety and vulnerability to collisions
- Substandard pedestrian and bicycle facilities
- Seismic vulnerability
What are the Challenges?
- Traffic congestion at the I-5 bridge currently lasts six hours and is
expected to increase to more than seven hours southbound and eight hours
northbound by the year 2030.
- On-time freight deliveries are compromised by congestion, hampering
productivity and efficiency.
- Buses traveling I-5 between Vancouver and Portland get stuck in
traffic and can become less reliable.
- Safety is deteriorating.
- About one crash occurs daily – a rate that is two times higher than
similar highways in Oregon and Washington. Crashes will grow with
more congestion.
- Many collisions can be attributed to short on-and off-ramps,
inadequate spaces for merging and weaving, and poor sight
distances on and near the I-5 bridge.
- A significant earthquake could cause bending, buckling or collapse
of the I-5 bridge itself or lead to soil liquefaction under the bridge
Current Status
In July 2008, local project partners selected a replacement bridge with light rail to
Clark College as the Locally Preferred Alternative (LPA).
The LPA was chosen based on information
in the Draft EIS, a recommendation from the 39-member Task Force and public comment. Having an LPA
demonstrates regional consensus about continuing project development and refining design of one alternative.
Over the next year, key decisions will be made on project elements, including: financing and
tolling, number of auxiliary lanes and design of the I-5 bridge, pedestrian and
bicycle pathway, high capacity transit alignment on Hayden Island and Vancouver,
sustainability plan and mitigation plan. Additional analysis of the
environmental and community effects of the LPA will be included in a Final EIS,
expected in late 2009.
