No lane or highway closures are scheduled, however motorists should anticipate some minor delays as equipment moves in and out of the project area at the junction of SR 20 and I-80.
The SR 20 on-ramp to westbound I-80 remains closed until further notice due to bridge construction activities.
The extended lane closures will help minimize the duration of the work and improve worker safety. The schedule is subject to change or may be delayed due to weather, availability of materials or other unexpected events.
