The Texas Department of Transportation (TxDOT) will close east- and westbound Farm-to-Market (FM) 545 in northeast Collin County just west of Blue Ridge at Sister Grove Creek in order to reconstruct and replace the bridge.

The closure will begin on Monday, Aug. 20 and continue through the next eight months.

At the same time the FM 545 bridge is closed, it will be necessary to close County Road 474 at the intersection of FM 545. This bridge is part of project to reconstruct and add 10-foot shoulders to FM 545 from one mile east to one mile west of FM 1827.

Portable message signs have been placed in advance of the closure to notify and guide drivers approaching the project.

Detours will be clearly marked.

TxDOT would like to thank area drivers for their continued patience and cooperation as crews work diligently to complete this vital project as soon, and as safely, as possible.
