Scheduled highway construction, an accident and a disabled vehicle backed up traffic on Interstate 35 southbound from Western Center Boulevard in north Fort Worth to downtown.
I-35W construction approaching Highway 121 was blocking the left lane of southbound traffic, according to traffic.com. Construction at Northeast 28th had traffic down to one lane between Northeast 28th and Pharr Street.
The Texas Department of Transportation is warning motorists to expect delays through Sunday from Pharr Street to Belknap due to the construction.
The left lane on I-35W will be closed until 6 p.m. Sunday for pavement repairs, according to the Transportation Department Web site. The ramp from Pharr to I-35W southbound will also be closed until 6 p.m. Sunday.
An accident at Northside Drive contributed to the traffic backup. A disabled car near Meacham Road also caused a slowdown.
