Dallas North Tollway planning further northern extensions

Plans advance for further extensions of the Dallas North Tollway taking it closer to the Oklahoma border. North Texas Tollway Authority (NTTA) have scheduled public meetings for discussion of alternate alignments for Phase 4B/5A. The area of study is in Collin, Denton and Grayson counties and between FM428 and FM121.

This is in addition to an already permitted 10km (6 mile) stretch from where the tollroad presently ends at US380 up to FM428 in Celina. That would take the DNT to 62km (38mi) in length

Beyond Celina/FM428 the alteratives are to head northwest angling across to meet US377 near Ray Roberts lake Cooke County called a  green route, or to continue trending due north along one of two alignments (orange/red and yellow/red) ending at FM121.

The northwest routing or green route is an extra 18km (11mi) and the other routes are around 16km (10mi). Both would take the DNT 80km (50mi) from its southern end near downtown Dallas and leave it only 40km (25mi) from the Oklahoma border in the middle of Lake Texoma

DNT forms a north-south corridor in about the center of strip roughly 50km to 60km (30mi to 40 miles) in width and parallel bounded by US75 on the east and I-35 on the west.

New segments of the Tollway will have all-electronic tolling. The rest of the tollway will likely have seen its last cash collection before the new sections open.
