The Calder Road overpass at Interstate 45 in League City will be demolished this weekend, causing traffic headaches as the freeway is closed and vehicles detoured to the feeder roads.

There will be four to five deputies from Galveston County’s Constable precincts working in the area around the demolition, League City spokeswoman Kristi Wyatt said. The city will also have a police officer at the intersection of Hobbs Road and Main Street as well as at Texas 3 and Main Street, she said.

There will also be two officers at Interstate 45 and Main Street, Wyatt said. The city’s police officers will manually control the traffic signals at each of those intersections, she said.

A map of the closure and detours can be found here. The work is part of a $21 million project to build a new flyover from the Gulf Freeway to Texas 96.

The city is preparing for a worst-case scenario with traffic, Wyatt said. It expects to experience lots of congestion during the closure, she said.

“We do think it’s going to be bad,” Wyatt said. “If you don’t have to go in that area, it’s best to avoid it.”

Although motorists won’t be able to cross Interstate 45 using Calder Road until next Thursday, Wyatt emphasized that League City's worst traffic problems stemming from the project will only be this weekend.

“Things will get better,” she said. “If people can just make it through the weekend then things will get better from there.”
