Concessionaire Cintra opened 13.5 miles of its North Tarrant Express managed lanes project in Dallas on Oct. 4, almost nine months ahead of schedule and with contractor change orders of only $5 million, according to Russell Zapalac, Chief Planning & Project Officer for Texas DOT.

The design-build contract held by Ferrovial and its subsidiary Webber Construction called for completion in June 2015. Working with 278 subcontractors, they rebuilt 13.5 miles of a highly congested segment of I-35 from Fort Worth to the Airport Freeway in Dallas under traffic.
