Case

Mersey Gateway Bridge

The Mersey Gateway Bridge is a new landmark toll bridge with cutting edge technological features. With toll income of the Mersey Gateway Bridge dependent on set speed thresholds, Dynniq designs, engineers and delivers the necessary systems.

The Mersey Gateway Bridge Project is one of the major current infrastructure projects in the world. A six lane toll bridge that relieves the congested and ageing Silver Jubilee bridge, connects communities, benefits the environment and provides important local economic stimulus.

The challenge

A new landmark toll bridge featuring cutting edge technology to monitor and control the operation of traffic on the bridge and approach roads.

Our solution

Dynniq delivers Traffic Control and Information Systems (TCIS), a Journey Time Measurement System (JTMS) and an Asset and Fault Management System.

The result

The six lane toll bridge will connect communities, present positive impacts on the environment and provide an important local economic stimulus. The bridge will shorten journey times by up to 10 minutes and improve congestion in the area.

A structure that will be iconic in function even more than in form. However, a fundamental operational design aspect poses a significant challenge to Dynniq’s client: Toll income for the Merseylink Consortium is dependent on meeting a set speed threshold. Dynniq takes charge of providing the technical systems to meet this challenge.

Connecting communities

Scheduled to open late in 2017, the cablestayed toll bridge measures 2.3 km, with towers up to 125 meters above the river bed. Once open, the bridge will shorten journey time by up to 10 minutes and reduce traffic over the Silver Jubilee Bridge by 80%. This benefits local residents in multiple ways. Reduced air pollution improves health, pedestrian and cycling routes will be expanded, and 4640 permanent jobs are projected to be created by the operation of the Gateway.

Dynniq manages crucial technological aspects of the project, working with two separate JTMS (Journey Time Management Systems) contractors to provide the Merseylink Consortium with solutions that are world firsts. For example two independent ANPR (Automatic Number Plate Recognition) systems will be fitted to prove the accuracy of the JTMS. This is vital in maintaining high average journey times and proving that these targets are consistently met.

Just in Time

A project of this scale requires intelligent planning. Dynniq has worked hard to identify areas where additional resources are needed to ensure the critical time path of the project is not disrupted. And, working closely with suppliers, Dynniq has ensured that contracts are met ‘just in time’ to minimise abortive work due to changes.

A reliable partner

Dynniq is proud of its contribution to this landmark project. We have worked closely and pro-actively with the consortium to design practical workable solutions across sometimes conflicting requirements.

For example issues regarding JTMS, CCTV and incident detection were identified early and suggested changes were accepted by the consortium. Open communications with the consortium and our project partners have led to solutions that are acceptable to all parties. This has helped to keep this project moving forward.
