Mérida, Yucatán — Starting at 8 a.m. Tuesday, east-to-west vehicular traffic will re-routed at the Progreso interchange.
Motorists should use precaution and allow extra time on alternate routes to reach their destinations, state police advised.
The above map shows how cars will travel on the Periférico from east to west.
The road system, just north of the Via Montejo project, was built 24 years ago when average daily traffic was 5,400 vehicles.
Work is expected to take another eight months, but in the end, drivers will enjoy a wide, four-lane road.
A ramp’s awkwardly steep slope will also be a thing of the past.
