M4 Smart Motorway Latest Update - Phase Two Of Construction Starts In 2019

Phase one of the project started in July 2018 and comprises the area west from Junctions 8/9 leading to Junction 12. While this is a significant piece of work in itself, phase two covering Junctions 8/9 eastwards into London and Junction 3 is a much more complex endeavour. Highways England are now preparing for Phase Two to get underway from May 2019.

Much of the M4 was originally built as a two-lane dual carriageway, and has been upgraded over the years. Eleven bridges over the motorway need to be replaced to make room for a new lane where there is no existing hard shoulder.

Where the motorway passes over, for example, the River Thames at Bray and the railway line to Windsor, bridges will need to be widened to support the new smart motorway. Two subways, including at Sipson, and several culverts that run under the motorway will also need work in order to accommodate the upgrade.

Some weekend closures will be required for bridge works. Road diversions for these works have been agreed with the local and statutory authorities. Full details will be communicated and posted well in advance.

There are several overnight full closures (usually 22:00 to 05:00) currently planned in January including:

▪ 15/01/2019 Junctions 10 to 8/9 Eastbound
