Project Summary

The M11 Junction 7A is a critical new infrastructure project funded through Highways England and Essex County Council to create a new junction between the existing junctions 7 at Harlow and 8 at Stanstead. The works were carried out to improve access to the area’s busy road network and help facilitate growth and better connectivity for residents, businesses and visitors.

The Detail

A single lane of traffic was always maintained by placing two-way traffic lights incrementally spread on each section of the motorway to manage the traffic. This method allowed us more time and space to widen the road gradually with the least impact. Pre-modelling work with Aecom and other stakeholders helped us predict the traffic flow through numerous assessments. These created likely scenarios that we presented to the transport division to offer reassurance that our TM would have the least impact over a shorter period. We utilised the vast engineering experience of the project team and supply chain partners to complete the delivery, lifting and installations with no issues arising. Opting for the larger crane meant we minimised lane closures, finishing the heavy lifting operation five days ahead of programme. Four overnight closures of the M11 were utilised to allow for the safe lifting and installation of the beams.

“The scale of the overall operation to complete these works was huge. Thankfully, we were able to call on the vast engineering experience of our team and the teams of our supply chain partners to complete the delivery, lifting and installations without any issues arising. We now shift our focus onto the next phase of the works in this important infrastructure project which will provide major benefits for Harlow and its surrounding areas.”
