One lane in each direction has been closed past the scene of multi-vehicle incident which happened in the early hours on Tuesday morning between junctions 26 and 27 of the M25, near Theydon Bois.
45 metres of concrete safety barrier needs to be replaced, along with 250 sq. metres of the road surface.
Work is well underway, and is being carried out both during the day and overnight, when additional lane closures are in place. The work involves:
- Breaking out and removing the damaged concrete barrier
- Installing a shutter (or mould), into which concrete will be poured and compacted to create the replacement concrete barrier
- Connecting the new barrier at each end to the existing safety barrier
- Removing equipment needed to install the barrier
- Resurface the road and removing the roadworks
How quickly the work can be completed depends on weather conditions, with temperature and rainfall both being crucial factors in how long it takes the concrete to reach full strength.
Highways Agency teams will work hard to keep three lanes open at all busy times, and up to date traffic information will be available on the Highways Agency’s website.
