A lane closure caused by construction along US 75 in Plano began Thursday morning and is expected to last into the weekend.

The southbound frontage road along US 75 will remain closed starting at Plano Parkway until 5 a.m. Saturday, a Texas Department of Transportation spokesperson said in an email.

Traffic will be directed to West Plano Parkway, then along southbound Alma Road to East Renner Road where drivers will then have access to southbound US 75.

The closures are making way for crews to erect a railroad bridge, the spokesperson said.
