Named as the “Project of the Year” at the 2019 Chartered Institution of Highways & Transportation (CIHT) North West Awards, the Travis Brow to A6 Link Road project has created an important new strategic highway connection in Stockport.
A core component of the Stockport Town Centre Access Plan (TCAP), one of Stockport Metropolitan Borough Council’s (SMBC) “most ambitious” programmes, the Link Road has improved the efficiency and reliability of the town’s highways network.
Our work has been praised for meeting the key objectives of “achieving best value, minimising disruption and efficient delivery”. Significantly, the implementation of an intelligent design solution enabled a two-lane dual-carriageway to be formed through a single arch.
The total construction programme was approximately £8m with the geotechnical works valued at circa £3m. Innovation was required to support the exposed rock face beneath the Viaduct foundations, whilst also restricting movements to negligible levels during the construction phase, which was a key Network Rail requirement.
Our intelligent solution utilised pre-stressed rock anchors, with a near vertical hard shotcrete facing. The retaining structure was then covered by mass concrete, to protect against vehicle impact and corrosion. The anchors were installed using a detailed construction sequence, employing vertical and horizontal excavation in distinct bays. In partnership with designers Mott McDonald, we value engineered the original SMBC outline design, resulting in substantial cost savings through the replacement of 225m of retaining walls, equating to 60% of the project’s original retaining walls.
“The retaining structures’ designs truly represent outstanding sustainable and best value solutions. GRAHAM has delivered the new Link Road in a collaborative, efficient and sustainable way, taking great care to minimise the impact of construction works on local stakeholders and the wider community.”
