As the Dallas North Tollway widening project continues, additional daily lane closures are expected for the coming week. Two north- and southbound left lanes on Dallas Parkway will closed as part of a project starting today and running through Feb. 22 from Parker Road to SH 121. These lane closures will occur daily from 9 a.m. to 3 p.m., according to a release from the North Texas Tollway Authority. Construction work along the Dallas North Tollway includes adding an additional travel lane in each direction of the tollway from SH 121 to the President George Bush Turnpike.
