Drivers navigating Highway 75 and Sweeney Hollow Road in Pinson now face a very different traffic light than they did earlier this week. The Alabama Department of Transportation has switched left turns at the intersection to protected-only operation, requiring a dedicated green arrow before drivers can cross oncoming lanes, after years of complaints about crashes and malfunctioning signals at the spot.
The changes came after an I-Team investigation examined the intersection following repeated driver complaints, according to WBMA. Jefferson County Sheriff's Office data cited in that report showed 19 crashes at the intersection in 2023, a number that jumped to 30 crashes in 2025. Local driver Brian McGinnis described the intersection as very dangerous, and another driver, Akilah Brown, told the station she witnessed a rear-end crash there.
Red-Light Running and Left-Turn Crashes Drove the Decision
ALDOT identified a pattern of red-light running and crashes involving left-turning drivers at the intersection, prompting the agency to change the signal operation this week, per the same WBMA report. Alacyia Hall said the switch to protected-only left turns was intended to reduce T-bone crashes, the type of collision that occurs when a turning vehicle is struck broadside by oncoming traffic.
The move lines up with national safety research. Federal Highway Administration studies show converting permissive left-turn signals to protected-only green arrows can reduce left-turn-related crashes by 15 percent to 50 percent at signalized intersections, according to the Federal Highway Administration. The agency's research also indicates that roughly 27 percent of all intersection crashes nationwide involve left-turning vehicles, with more than two-thirds of those happening at signalized intersections.
Crash Data Since June Shows a Mixed Early Picture
Crash data gathered since June recorded two crashes in June, one in July, and two in August, for five total crashes over that stretch, the WBMA report found. None of the five crashes were fatal, though one reported injury was recorded. ALDOT has said it is too soon to know whether the new signal pattern will reduce crashes over the long term.
The agency plans to review crash data again after a couple of months, or possibly six, per that same report. If crashes continue, ALDOT said it will consider speed as a contributing factor and may involve law enforcement. State Route 75 and Sweeney Hollow Road fall under ALDOT's East Central Region, which manages highway engineering, maintenance, and traffic safety improvements across Jefferson County and ten neighboring central Alabama counties, according to the Alabama Department of Transportation.
A Corridor Already Under Pressure
The Jefferson County Sheriff's Office provides primary law enforcement and crash response for unincorporated areas and municipalities without their own police departments in northern Jefferson County, including Pinson, which is why its figures — rather than a city department's — tracked the crash counts at the intersection. Pinson was incorporated in March 2004 and recorded a population of 7,215 in the 2020 U.S. Census, according to the U.S. Census Bureau, covering roughly 10.6 square miles as a relatively young suburban city adapting to growing traffic pressures.
Highway 75 itself stretches 113.2 miles from Interstate 59 in eastern Birmingham through Pinson and Blount County to the Georgia state line, serving as a primary multi-lane commuter arterial before narrowing to a rural two-lane road further north, per Wikipedia. That commuter role is about to intensify. On September 29, ALDOT and Governor Kay Ivey officially opened the first 1.88-mile segment of the Birmingham Northern Beltline, the future I-422, directly connecting State Route 79 to State Route 75 near Pinson, according to the ALDOT News Hub.
More Construction — and More Traffic — on the Way
ALDOT has already announced plans to award contracts in 2027 for the next eight-mile extension of the Northern Beltline, which will push west toward U.S. Highway 31 in Gardendale. The full 52-mile interstate loop is projected to cost several billion dollars once complete. For a corridor that already handles heavy commuter volume, the new beltline connection raises the question of whether additional vehicles routed onto Highway 75 near Pinson will add further strain to the Sweeney Hollow Road intersection just as ALDOT begins monitoring the effects of its signal change.
A shooting also occurred in Pinson. Statewide, Alabama recorded 967 traffic fatalities in 2024, down slightly from 975 in 2023, with non-seatbelt use cited in nearly 60 percent of vehicle occupant deaths, according to ALDOT figures.
Residents React to the New Signal Pattern
For now, residents who use the intersection regularly are watching to see whether the protected-only arrows make a visible difference. Yaquelin Herrera urged drivers to slow down and follow traffic laws regardless of the signal changes, while Larry Russell said the adjustments could improve safety at the intersection. ALDOT has not said whether further changes are planned beyond its upcoming crash-data review.
