Starting Wednesday, those commuting via southbound SH-4/Piedmont Rd. between N.W. 178th St. and N.W. 164th St. in Piedmont should brace for minor delays as the roadway will narrow to one lane due to construction efforts set to continue throughout the rest of the year. Reports from Oklahoma Department of Transportation indicate an ongoing project will be the cause of the commuting bottleneck. Drivers traversing SH-4 will also face altered traffic patterns between NW 122nd and SH-3 as north and southbound lanes have been shifted onto a new alignment where changing conditions should be anticipated.

In Norman, I-35 roadway construction is also underway, with the left lane of northbound I-35 near Indian Hills Rd. closing from 7 p.m. to 5 a.m. until Friday. Alluding to the necessity of the work, the initial announcement stressed the importance of surface work being done during these nocturnal hours. Commuters are advised to seek alternative routes or allow for additional time through the construction zones to minimize disruptions to their schedules.

Ongoing maintenance and upgrades of I-40 are significantly impacting traffic with narrowed lanes and various ramp closures between Meridian Ave. and May Ave. over I-44. East and westbound traffic on I-40 is constricted, specifically around Douglas Blvd. in Midwest City, sustaining two lanes in each direction with lane shifts and intermittent ramp closures that are slated to persist through 2025.

Additional disruptions include a full closure of east and westbound SH-37/S.E. 4th St. between Broadway Ave. and Tower Dr. in Moore, destined to persist through the summer of 2026 due to a railroad bridge project. Lanes on US-77 in Norman are expected to suffer intermittent night-time closures until mid-November as resurfacing work is completed, according to state transportation officials.

Travelers are further cautioned about the narrowing of roads in and around El Reno, where SH-66 and US-81 will pare down to one lane in each direction for roundabout construction through 2025. Additionally, bridge replacements and intersection expansions are also leading to road narrows and closures near SH-9E and at the intersection of Danforth Rd. and Kelly Ave. in Edmond, which persist through Spring 2026. Commuters are encouraged to monitor traffic advisories and plan accordingly for these extensive and continued infrastructure improvements.
