New traffic signal coming to Highway 280, Overton Road

BIRMINGHAM, Ala. (WIAT) — The Alabama Department of Transportation will be installing a new traffic signal Friday at the intersection of U.S. Highway 280 and Overton Road.

The installation will begin at 9:00 a.m. Friday morning and last for approximately three hours, weather permitting, according to ALDOT. During the installation, both the U-turn and left turn lanes will be closed until installation is complete.

ALDOT wants to remind drivers on 280 that U-turns are prohibited at the intersections of Rocky Ridge Road and Green Valley Road. They also suggest using the Pumphouse Road interchange as an alternate route for those who would normally make a U-turn at Overton Road.

The new signal, which will have four signal heads, is only the second of it’s kind in the state of Alabama and the first to be installed on an Alabama state highway.

“We’ve seen a lot of motorists that need to make that left turn onto Overton Road,” Brian Davis with ALDOT said. “We’ve gone back and looked at the gaps there and seen that we have an opportunity to add a section to the signal head to allow that move to not only be made in a protected fashion, but at a permissive fashion.”

The new, fourth signal head will be a flashing yellow turn signal which will allow drivers to turn onto Overton Road as long as there is no oncoming traffic on 280 westbound.

“We’re trying to make progression along 280, so we felt like this is the best move. People are accustomed to making that left permissively, anyway,” Davis said, referring to the traffic signal at the intersection before Highway 280 was modified. “This helps us clear that queue without having to change the cycle time on 280.”

According to an information sheet obtained by WIAT 42 News, here is the explanation to what each signal head will mean:

  • Steady Red Arrow – drivers must stop.
  • Steady Yellow Arrow – warning that the signal is about to turn red. Do not enter the intersection if you can safely stop.
  • Flashing Yellow Arrow – drivers are allowed to turn left after yielding to oncoming traffic and pedestrians. The oncoming traffic has a green indication, drivers must wait for an adequate gap in the oncoming traffic to complete their turn.
  • Steady Green Arrow – drivers making a turn have the right of way.

ALDOT wants to be clear that the flashing yellow arrow only applies to those making a left turn and does not apply to those making a U-turn at the Overton Road intersection.

In 2015, similar signals are planned to be added to stretches of highways in Fairhope along routes that lead to the Alabama and Florida Gulf Coasts.
