(June 10, 2021) All lanes of the eastbound US 380 frontage road between north - and - southbound Dallas Pkwy closed from 9 p.m. Friday, June 11 through 6 a.m. Saturday, June 12 while NTTA constructs the new Tollway overpass.

  • Take the Dallas North Tollway exit and turn right onto southbound Dallas Pkwy.  Continue to PGA Pkwy., take the U-turn, and continue north to US 380 and turn right. See the attached map from NTTA (PDF).
