The biggest and last of the major traffic pattern changes in the renovation of the highway interchange between state roads 826 and 836, the Palmetto and the Dolphin, goes into effect Sunday.
Workers will open new soaring flyovers, the centerpiece of the $560 million renovation of the interchange located near Miami International Airport. The project is expected to be completed sometime next year.
Travel lanes will be closed in advance of the opening of the flyovers. The weekend shift comes one week after another major traffic shift, when the westbound 836 travel lanes between Northwest 57th and 87th avenues were moved to the north side of the newly constructed roadway.
Meanwhile, the entrance ramp to eastbound 836 from northbound Northwest 57th Avenue will be closed for paving through Thursday from 10 p.m. to 5 a.m. each night. The eastbound 836 exit ramp to 57th Avenue also will be closed for paving during the same time period, as will be the westbound 836 exit ramp to Northwest 107th Avenue.
Never miss a local story.

Also on the turnpike, one or two lanes in each direction between Killian Parkway and Eureka Drive will be closed nightly between 9 p.m. and 5 a.m. through Thursday. Both closures are for widening and toll express lane construction.
