Portland I-5 Closure Set to Disrupt Commutes as City Considers Passes

The Portland City Council will vote next week on an emergency ordinance to provide all 9,000 city employees with TriMet transit passes, aiming to maintain municipal staffing during a five-week closure of southbound Interstate 5 through the Rose Quarter beginning September 11.

As drivers across the Portland metro area brace for what transportation officials warn could be some of the worst traffic that the area has seen in some time, City Hall is moving quickly to rewrite the daily commute for its workforce. Mayor Keith Wilson added an emergency ordinance to the consent agenda for the upcoming September 2 City Council meeting, proposing a one-year pilot program to issue transit fare cards to every municipal employee.

Emergency Transit Program and Budget Costs

The proposed one-year pilot would run through August 31, 2027, according to municipal budget documents. It is designed to cover full transit access across the metropolitan network, including TriMet buses, MAX and WES trains, and C-Tran local service.

Implementing the program would cost the city up to an additional $245,000. When broken down per worker, the cost to the municipality is estimated at $55 per employee.

For the past 30 years, the city has operated the Trip Reduction Incentive Program to encourage public transit use and cut down on single-occupant vehicle commuting, offering a 50% discount that currently enrolls about 500 workers. Under the new pilot, those existing participants would receive reimbursements for the unused portions of their passes.

The Impending Rose Quarter Shutdown on Interstate 5

The immediate catalyst for the emergency transit push is the upcoming closure of all southbound lanes of Interstate 5 through the Rose Quarter. The shutdown begins on September 11 and is scheduled to last for approximately five weeks as crews execute a major repaving and upgrade initiative.

According to the Oregon Department of Transportation, the project includes shutting down the southbound I-5 connector from I-405 to I-84, alongside several local on-ramps. Drivers heading southbound will be detoured across the Fremont Bridge, while local traffic will have the option to exit at Broadway.

Crews will replace concrete on the elevated roadway and complete repairs that have not been done in decades. Transportation officials warn that backups could stretch across the river into Vancouver, making it imperative for commuters to seek alternative routes.

City Staffing and Remote Work Pressures

Beyond navigating the immediate highway construction bottleneck, city leaders face broader structural challenges regarding downtown office attendance and transit usage. Municipal officials have ordered workers to return to physical offices following years of remote work, though the largest employee union has pushed back against the mandate.

The city is looking for ways to help employees shift their trips so we can maintain staffing levels and keep city services running smoothly during the disruption, mayoral spokeswoman Carrie Belding wrote to reporters, as reported by Willamette Week.

Data from a 2024 employee survey underscore the commuting habits municipal leaders hope to alter: approximately 45% of city workers primarily drove to work, while 24% used public transit and 21.5% walked or biked. Notably, more than half of those who drove indicated that stronger incentives could persuade them to switch to alternative transportation.

Broader Transit Realities and Future Construction Phases

The municipal transit push arrives as TriMet grapples with its own financial and ridership hurdles in the wake of the pandemic, prompting service reductions across the metro area.

Even after the upcoming southbound repairs conclude, motorists will face additional disruption. The Oregon Department of Transportation expects crews to tackle the northbound lanes sometime in mid-to-late 2027 as part of the broader I-5 Rose Quarter Improvement Project.
