I-5 Southbound Closure Triggers Major Commute Disruptions
The Oregon Department of Transportation (ODOT) has shut all southbound lanes of Interstate 5 through Portland’s Rose Quarter for a five-week period. The closure began the night before the first weekday commute, affecting a nearly two-mile stretch between I-405 and I-84. Drivers are being redirected to alternate freeways and city streets, with ODOT warning that rush-hour travel could take up to three times longer than normal.
ODOT’s Response and Traffic Management Plans
ODOT spokesperson Rose Gerber explained that the project replaces the freeway’s concrete surface for the first time since 1985. Initially, traffic was reduced to a single lane near Rosa Parks Way while striping changes and on-ramp adjustments were made; a second lane has since reopened. Gerber said ODOT is updating signage to clearly indicate lane availability before drivers reach I-405.
ODOT also urged motorists to use the “zipper merge” technique, allowing both lanes to stay open until the merge point to shorten backups. David House, another ODOT spokesperson, noted that the agency and the Portland Bureau of Transportation (PBOT) will monitor traffic volumes and adjust signals as needed, seeking patterns that could aid travelers.
Commuter Reactions and On-the-Ground Adjustments
Portland residents are adapting in varied ways. Jason Marshall, who normally drives two miles to work, said his commute can swing from two minutes to 25 minutes depending on traffic. Anna Henning is employing stress-reduction techniques to cope with longer trips, while Anise Frederick plans to work from home to avoid gridlock altogether. Many commuters report shifting travel times, using alternative routes such as the Morrison and Steel bridges, or opting for public transit and cycling.
