What to expect

Travelers will see nighttime I-5 lane reductions between Maytown Road and Old Highway 99, Monday through Friday. The speed limit on I-5 will be reduced from 70 mph to 55 mph from milepost 88.9 to 95.7 when crews are working. Additionally, Scatter Creek and Maytown rest areas will close overnight. Both rest areas will reopen for daytime use.
