What to expect

A shoe-fly detour or bypass will be constructed to divert traffic around the work zone. This will keep travelers moving while construction is occurring. Additionally, beginning summer 2020, the posted speed limit for this detour will be 25 mph. This speed limit reduction will remain in place until construction is completed in fall 2021.

While no major delays are scheduled, there will be around-the-clock flagging which permits delays up to 20 minutes for approximately 48 hours, however, these delays are not scheduled until early 2021.
