The tender involves construction work to raise parts of the road above the flood plain, incorporating activities such as tarmac perforation, the building of retaining walls, and installing new carriageways. This opportunity, suited for the highway construction and concrete sectors, is at the Tender stage and is open for submissions until 19th June 2025. The contract is due to be awarded by 14th July 2025, with the entire process being conducted electronically through the open procurement method, ensuring accessibility for interested parties located around the North Conwy Valley region. This tender presents a significant opportunity for construction companies specialising in infrastructure development, reinforced concrete works, and road construction. Businesses equipped with the expertise in handling flood-prone areas and masonry work, particularly those familiar with regional constructions, stand a strong chance of leveraging this opportunity to grow their portfolios and establish a solid presence in local government projects. The operation's scope necessitates suppliers skilled in various construction types, including reinforced-concrete structures and high-level roadworks, contributing to improved regional connectivity and infrastructure resilience. ## Notice The B5106 running from Dolgarrog to Trefriw regularly closes during storm events due to high water levels coming from the flood plain.
