Yet another major traffic pattern change is coming to State Road 836, the Dolphin Expressway, that will force commuters to be on their toes.
Beginning Saturday at dawn, drivers going westbound on 836 and wanting to exit at NW 72nd Avenue will have to leave the highway at a new ramp just after NW 57th Avenue, said Oscar González, spokesman for the State Roads 836-826 interchange reconstruction project.
The shift is part of the $560 million overhaul of one of the busiest interchanges in South Florida, a maze of soaring ramps and flyovers near Miami International Airport.
“The biggest change is for those people exiting at 72nd Avenue,” González said.“The change is that now they will have to exit about half a mile earlier from the current exit ramp. If they miss that exit they will have to continue on 836.”
Drivers who miss the new exit can continue west and exit at Northwest 87th Avenue/12th Street and head east to 72 Avenue.
Currently, drivers continue westbound on 836, and at 72nd Avenue take the exit ramp.
Another change will involve a shift of all westbound traffic to the left onto new lanes on 836 after the new 72nd Avenue ramp.
This shift involves the so-called split in lanes on 836. The three on the right take traffic westbound on 836 and the two on the left lead vehicles to 826, the Palmetto Expressway.
“The split is moved farther west from where it was before,” González said.
The interchange reconstruction project began in 2009 and is now currently expected to be completed late next year.
Project limits are on 826 from approximately just north of Southwest eighth Street to Northwest 25th Street.
On 836, project limits extend from just east of Northwest 87th Avenue to Northwest 57th Avenue.
The work involves widening, replacement of the existing interchange with a new four-level interchange, and overhaul and modification of interchanges on 826 at Flagler Street and on 836 at Milam Dairy Road and Northwest 72ndAvenue.
