MIAMI (CBSMiami) -- Some new hi-tech improvements are coming to the Dolphin Expressway (SR 836) meant to help drivers get home safely.
With South Florida's rainy weather being a constant problem as well as nighttime driving conditions, new lane markings are being put in place on the expressway lanes.
The new materials on the markings will better reflect car headlights to help drivers stay in their proper lanes.
To help alert distracted or drowsy drivers, new rumble strips were added into the shoulder lane markings.This helps prevent lane drifting. If a driver strays from the travel lane, the strips rumble the car which helps get the driver's attention.
A first in Miami-Dade County, solar powered road pavement markings with illuminated white LED's will be embedded in the highway to help guide drivers in bad weather or fog.
To help control speeding, radar speed indicator signs on the highway will warn drivers they may be traveling over the speed limit.
The additions are part of a $880 million Five-Year Work Program meant to improve traffic flow and congestion.
