Interstate Bridge Portland: Visiting Hours, Tickets, and Historical Site Guide
Date: 04/07/2025
Introduction: The Interstate Bridge’s Legacy and Modern Role
The Interstate Bridge is an iconic structure spanning the Columbia River, connecting Portland, Oregon, and Vancouver, Washington. Since its original opening in 1917 and the addition of a second span in 1958, this bridge has been a crucial artery for the Pacific Northwest—facilitating commerce, commuting, and cultural exchange between two thriving cities. With over 130,000 vehicles crossing daily, the bridge is a testament to the region’s growth and a symbol of unity and resilience.
Yet, as traffic volumes soar and the bridge ages, modernization has become essential. The ongoing Interstate Bridge Replacement Project seeks to deliver a seismically resilient, multimodal crossing with expanded capacity and dedicated transit, cycling, and pedestrian routes. This guide provides detailed information for visitors and commuters, including access tips, historical context, best viewing areas, construction updates, and travel advice to help you make the most of your experience.

Historical Background and Development
The Interstate Bridge was inaugurated in 1917 as the first fixed crossing over the Columbia River between Oregon and Washington. Its original steel vertical-lift span was a marvel of early 20th-century engineering. In response to growing traffic, a second span was added in 1958, integrating the bridge into the then-new Interstate 5—now the West Coast’s primary north-south corridor (Oregon History Project).
Since then, the bridge has enabled a dramatic increase in cross-state mobility and commerce. Daily traffic grew from 33,000 vehicles in the 1960s to over 130,000 in recent years (Washington State Standard).
Visiting the Interstate Bridge: Hours, Access, and Tips
Visiting Hours and Ticket Information
- Open 24/7: The bridge is available at all hours for vehicles, pedestrians, and cyclists.

Getting There and Accessibility
- By Car: Access via Interstate 5 from either downtown Portland or Vancouver. Parking is available at nearby locations such as Tom McCall Waterfront Park (Portland) and Esther Short Park (Vancouver).
- By Bike/On Foot: The bridge features narrow sidewalks adjacent to traffic. Cyclists and pedestrians should exercise caution, especially during peak hours or bridge lift operations.
- Public Transit: TriMet (Portland) and C-TRAN (Vancouver) run bus routes across the bridge. A future light rail extension is planned as part of the replacement project (Wikipedia, Interstate Bridge Project).
- Accessibility: The sidewalks are not ADA-compliant; those with mobility impairments may find crossing challenging.
Travel Tips
- Avoid Rush Hours: Peak congestion occurs 6:30–9:30 a.m. and 3:00–7:00 p.m. on weekdays.
- Bridge Lifts: The bridge’s lift span can delay traffic for up to 20 minutes. For real-time lift schedules, check the Oregon Department of Transportation.
- Safety: Remain alert on narrow sidewalks; wear visible clothing and consider alternative crossings if you require fully accessible facilities.

Economic and Regional Importance
The Interstate Bridge is indispensable for regional commuters and national freight. Over $132 million in goods cross daily, representing a significant share of Oregon and Washington’s economic output (Hoodline; Interstate Bridge Replacement Program FAQ).
Structural & Safety Challenges
Despite its historical importance, the bridge’s narrow lanes, lack of safety shoulders, and seismic vulnerability pose safety concerns (Washington State Standard). The current structure is considered functionally obsolete and unlikely to withstand a major earthquake. Modernization is not only necessary for safety, but also to support increased multimodal transportation.
The Replacement Project: Vision and Timeline
Project Scope
- Location: Two new bridges west of current spans.
- Capacity: Three through lanes each way, wider lanes (12 ft), safety shoulders, and auxiliary lanes.
- Multimodal Features: 1.9-mile light rail extension, improved pedestrian/cyclist facilities.
- Seismic Resilience: Built to modern earthquake standards.
- Urban Connectivity: Vancouver’s I-5 “lid” will create green space and a public transit hub (OPB).
Funding
- Estimated Cost: $5–$7.5 billion.
- Secured Funding: $1.5 billion federal grant, $600 million Mega Grant, $1 billion each from Oregon and Washington; additional funds via tolling and federal transit programs (Hoodline).
Timeline
- 2024: Draft Supplemental Environmental Impact Statement (SEIS) released.
- 2025: SEIS finalized.
- 2026: Pre-construction begins.
- 2027: In-water construction commences.
- 2032: Anticipated completion (OPB).
Traffic and Tolling
- Tolls: Variable-rate tolling may begin by 2026, with discounts for low-income drivers under consideration (KATU News).
- Traffic Impacts: Expect lane closures and detours during construction; monitor Interstate Bridge Project for updates.
Social, Environmental, and Community Considerations
- Community Impacts: Replacement may affect up to 43 homes and 36 businesses (Washington State Standard).
- Environmental Review: Evaluating drawbridge vs. fixed-span options; public input is ongoing (Interstate Bridge Replacement Program).
- Public Engagement: Extensive opportunities for residents to participate via hearings and open houses (Interstate Bridge Replacement Program).
