A flagging operation will begin on Byron Nelson Boulevard, or Business 114, in Roanoke starting March 5 at 7 a.m.

The operation will stretch from Oak Street to Cannon Parkway ahead of a bridge deck pour scheduled for March 6. Traffic will be reduced to one lane, and flaggers will direct traffic to allow for two-way traffic control. Drivers are advised to allow extra time or choose an alternate route during this time.

The operation is part of ongoing construction of a more than $30 Texas Department of Transportation project to overhaul a 1.12-mile portion of Hwy. 377. The project includes reconstruction and widening of Hwy. 377 from a two-lane rural road to a four-lane, divided roadway with raised medians and sidewalks, according to TxDOT.
