PLANO (CBSDFW.COM) –  The North Texas Tollway Authority is lowering speed limits on the Dallas North Tollway between Beltline and Frankford Roads for safety as a new phase of construction gets underway on the DNT.

Roadway signage will be changed to reflect the new, lowered speed limit of 55 mph in this area. The lowered speed limit will be enforced throughout construction according to a NTTA news release.

“NTTA is lowering speed limits so workers and drivers can operate safely in the construction zone,” said NTTA Assistant Executive Director of Infrastructure Elizabeth Mow. “Once completed, these projects will provide a significant benefit to the traveling public. We appreciate our customers’ increased attention within work zones.”

A reminder that lowered speed limits (60 mph) remain in effect on the DNT between the President George Bush Turnpike and Sam Rayburn Tollway and on PGBT between the DNT and State Highway 75 as improvements continue in those areas.

The latest information about the PGBT and DNT projects is available here, via email at or by calling (972) 628-3134.
