The closures are needed because the joints along the bridges are leaking water, the safety barriers appear to be substandard, and there is no kerb drainage or gully installed over the deck causing water to build up along the verges which is damaging the substructure. Dealing with these issues now ensures the roads (the roundabout and on the M4 below) will be safer for all users as we head into the winter weather.
Phase 1 – North-easterly roadworks over Bath Road/M4 Junction 12 roundabout
The first phase of the works focuses on the north-easterly direction (from Theale towards Reading), with closures affecting the west bridge and northbound traffic over the Bath Road/M4 Junction 12 roundabout, where essential structural maintenance needs to be carried out by National Highways.
Daytime: The roundabout will remain open and accessible but with lane closures.
Overnight: Certain sections of the roundabout will be fully closed with no access.
Key details:
• Route closures towards Reading from Theale: The recommended diversion route for vehicles, including HGVs, is via Theale, Aldermaston, Tadley towards Basingstoke, then back up to Reading (A4, A340, A339, A33, A4155, A4). Other routes are available but might not be suitable for all vehicles. Please plan your journey in advance, ensuring routes are suitable for your vehicle’s height and weight.
