The new traffic flow change on State Road 836, the Dolphin Expressway, will be put to a test on Monday.
The change, made on Sunday, was delayed the previous weekend because of rain and reset for this weekend, according to Oscar González, a project spokesman.
The shift is part of the ongoing $560-million overhaul of a massive interchange between 836 and State Road 826, the Palmetto Expressway, near Miami International Airport.
Under the new traffic pattern, drivers will have to take a different exit to get to West Flagler Street and NW 87th Avenue, if driving west on 836.
Never miss a local story.
Currently, drivers on westbound 836 who are headed to West Flagler and 87th Avenue stay on the right lanes of the highway, go past the 72nd Avenue exit ramp and then look for their respective exits.
Once the shift takes place, drivers on westbound 836 will have to exit at the 72nd Avenue ramp and then bear to the left to access a new temporary lane that will take them to 87th Avenue and West Flagler Street, González said.
The change will be in place for about five months and will enable workers to carry out other project work including demolition of a bridge.
