A project to convert the Southern Terminal Toll Plaza located in Sumner County at mile marker 16.5 I-35/KTA to open road tolling will begin with the reconstruction (and temporary closing of) the 30th Street South Bridge over the Turnpike on September 17, 2018.

Construction will involve building new northbound cash lanes east of the existing lanes and new highway speed electronic lanes for both north and southbound traffic. Included in the project is reconstruction of two bridges crossing I-35/KTA – the 30th Street South Bridge (mile marker 17) followed by the 40th Street South Bridge (mile marker 16).

The Turnpike will be using Smart Work Zone technology to provide advanced notice of slowed or stopped traffic to travelers approaching the construction zone. The speed limit approaching the project will be reduced to 55 mph with further reductions, as posted, through the toll plaza itself. Drivers are encouraged to stay alert and avoid distractions within the work zone.

Open road tolling is a method of toll collection which allows electronic customers who have K-TAGs or other compatible transponders to move through the toll plaza at highway speeds. Travelers who prefer to pay with cash can slow and pull to the right, well out of way of highway traffic. (View a video simulation here.)

The project contract was awarded to Venture Corporation, Great Bend, KS for $15,265,817.43 in August 2018. This is the third of three mainline toll plazas being converted to open road tolling. Eastern Terminal, just west of Kansas City, was completed in 2017 and construction of the East Topeka toll plaza is scheduled for completion later this fall.
