There will be lots of ways to pay – a simple pre-pay account, where drivers can save up to a third on each crossing, and also online, by phone and at selected retail outlets'.Highways Agency project manager Nigel Gray said: “Completing this first phase of construction successfully is a big milestone in our work to improve the Dartford Crossing for the 170,000 drivers that use it every day. We’ve worked hard to install these five gantries in a way that keeps traffic disruption to an absolute minimum, and we’ll continue this focus as we move on to the next phase of work.”Erwan Huerre, transition manager at Connect Plus, added: “The delivery of the charging gantries is an important milestone in the introduction of Dart Charge as it enables the installation of the new charging technology. To achieve this great success, Connect Plus has overcome a number of challenges including the non conventional design of the gantries on the approach to the tunnels and the complex coordination of works required to make it a painless experience to the road user.”The gantries will house the technology that will drive Dart Charge. One gantry will carry signage, and the other four will hold equipment to detect and identify the vehicles passing under them. Work on installing this equipment will now begin, and will be carried out using restrictions in one of the tunnels or on the QEII bridge. When the QEII bridge is closed, the east bore will be used for southbound traffic.Once installed, the new cameras will begin their testing phase before going live later this year.
