Another weekend closing of Interstate 45 through downtown looms, though transportation officials do not not expect the shutdown to darken spirits for the city’s holiday lighting ceremony.

Visitors to the area from Friday night through Sunday, however, should expect some detours, just in case.

The third of four planned closings of I-45 from U.S. 59 to interstate 10 will start at 9 p.m. Friday, according to the Texas Department of Transportation. The closing is needed as crews rebuild the West Dallas bridge over the freeway, which was damaged in September.

TxDOT officials said the road will open by 5 a.m. Monday.

City officials said they do not expect the closing to have any impact on traffic to and from the holiday lighting, expected to last until 8 p.m. on Friday night outside City Hall.

The final weekend closing for the bridge work is scheduled for Dec. 9-12. West Dallas is expected to open in late December or early January, at the same time as entrance ramps from Houston Avenue and Allen Parkway to southbound I-45.
