Overnight closures and temporary speed limits are set to feature in the improvement work this year and next at the M25 junction at the top of Reigate Hill.
The information is set out in a proposed traffic management order published last week on the Surrey County Council website.
As is normal, the order doesn’t give specific dates for work, but rather a permitted window – in this case from July 2019 to December 2020.
Advance warning signs will be displayed, and roadworks.org will publish information, before any phases of work get under way.
The proposed order states that night-time closures to quadrants of the roundabout, as well as sections of local roads including the A217 and Wray Lane, are “anticipated” to be needed between 9pm and 6am.
Diversion routes have been drawn up.
At other times drivers may face temporary speed limits of 20 miles per hour when work is taking place on the A217 north and south of the junction.
The improvement project is designed and funded by Highways England, although much of the work will take place on roads controlled by Surrey County Council. The project page says:
“Works will include:
- upgrading the traffic signal installation throughout the junction
- adding an extra lane on the A217 northbound approach
- widening into the existing verge and extending the anti-clockwise exit slip road
- adding an extra lane on the north circulatory section of the roundabout
- widening lanes on the east and west bridge section of the roundabout
- improving road signs and markings
- widening and realignment on the A217 southbound to two lanes that merge prior to Wray Lane.”
As well as having two lanes that will now come down Reigate Hill until just before the Wray Lane junction, a slip road will also branch off towards Merstham.
An earlier idea to run two lanes further down Reigate Hill, so as to accommodate more traffic waiting for the level crossing, was dropped. That proposal would have involved one of the two northbound lanes starting later up the hill.
The Highways England webpage still lists “spring 2019” as the start of the project: and some enabling work such as surveying did take place in March.
The project page gives “spring 2020” as the completion date.
