Coming Soon! Crews are expected to stripe eastbound Dyer Road underneath the freeway to reopen the street to three lanes. Once complete, crews will place concrete barriers along eastbound and westbound MacArthur Boulevard to shift traffic towards the outside and reduce the street to two lanes in each direction. This will allow crews to safely perform work in the median.

Additional information will be provided in future communications.

Crews are expected to perform paving activities along the retaining wall near the northbound (NB) McFadden Avenue off-ramp. This work will require closing the NB McFadden Avenue off-ramp, Edinger Avenue on-ramp, and two outside lanes between these ramps from 9 p.m. to 5 a.m. nightly, Monday, Aug. 3 through Friday, Aug. 7.

Exciting news! Crews have successfully installed and activated new traffic signals on Newport Avenue at the northbound I-5 on-ramp intersection. This effort required tremendous planning and coordination between the project team, the contractor, and utility partners and will improve traffic flow for motorists.

We thank and appreciate the public for allowing crews to complete the work safely and keep the project moving forward.
