Work Continues on Cashless Tolling Conversion

Crews continue to work on the conversion to cashless tolling on the Dallas North Tollway between Interstate 635 and Parker Road. In late June and early July, work zones were set up to allow the crews to construct the outside columns for the main lane gantries at Trinity Mills Road and Parker Road. Several evening lane closures were required to restripe portions of the main lanes and to place concrete barriers. The construction crews also established work zones on each of the entrance and exit ramps at Spring Valley Road, Beltline Road, Keller Springs Road and Frankford Road.  All work zones allow for traffic to flow freely, and all toll plazas will continue to provide cash toll collection along with TollTag until Dec. 11, 2010.

Multiple work zones along the corridor allow construction crews to move from location to location in a cascading pattern. One crew focuses on one part of the process (e.g., constructing the column foundation) and another crew then completes the next part of the process (e.g., constructing the formwork for the column).  Quite often drivers may not see crews in the work zone of a particular ramp, since most of the initial work is below ground behind the barrier. Drivers are encouraged to drive safely and follow posted speed limits in all work zones along the tollroad and to abide by all warning signs.

As construction progresses and the columns are constructed in each work zone (ramps and main lane gantries), crews will move the work zones to the other side of the road or ramp. The NTTA anticipates that the current schedule for Trinity Mills Road and Parker Road will involve moving the work zone to the median in September 2010. The work zones at the ramps will switch to the other side of the ramp as work begins on new columns.
