A12 to A120 widening traffic management during construction factsheet

A12 scheme summary

The proposed changes to this stretch of the A12 road include: n improvements to junctions n construction of new junctions 21, 22 19 and 25 and 24 providing access to the A12

both northbound and southbound n widening of the from two to three lanes in n creation of two bypasses, each direction from Hatfield one between junctions 22 Peverel to and 23 and another between

junctions 24 and junction 25 n removal of existing junctions n new and improved existing walking, 20a, 20b and 23 cycling and horse-riding routes

www.highwaysengland.co.uk/A12 Our commitment to you n We exist to connect the country, and customer service is one of our priorities n Customer satisfaction and safety are critical components of our vision for the future n We care about our customers and are committed to improving our service to you n We’re committed to improving our customer experience through roadworks by maximising safety (for both road users and road workers) and minimising disruption caused by roadworks schemes

What is traffic It can include: n narrowing of road lanes and management some speed restrictions so that traffic can continue to pass while Traffic management is work is carried out where the traffic is directed n diversions which take traffic away from construction areas around disruption so that n where construction of new roads it can continue to flow as or bypasses are needed, the new freely as possible during elements are completed first and the construction of large traffic continues on existing roads n night-time road and slip road infrastructure projects, closures or occasional weekend like the A12 Chelmsford to closures with local diversions for A120 proposed widening traffic travelling at off-peak time to scheme. allow for safe construction work on bridges How we will communicate traffic management during construction

The A12 Chelmsford to A120 widening is a major infrastructure project and involves an investment of around £1 billion. When the proposed scheme is in its construction phase, we will use a range of traffic management measures to help keep traffic moving throughout the local area. n When road works are required, n Speed restrictions will be put in we will give customers, drivers, place from when construction businesses and residents as starts until completion on the much notice as possible of up main A12 carriageways requiring and coming roadworks so they upgrading can plan ahead n Where needed, lane closures or n We plan to keep two lanes open full road closures will be in place in each direction on the A12 overnight as these are the times during the day, when the road is when traffic levels are lower busier n All diversion routes for full road n We will use clear signage and closures will be pre-signed and electronic signs to ensure people advance warnings signs will be are aware of roadworks installed before any closure dates n We will use ‘travel time’ message n There will be announcements signs so you are kept up to date on our website and on social while on your journey and aware media on all traffic management of any delays on the route measures and diversions

What to expect On new bypass sections between junctions 22 and 23, We are sorry for any inconvenience and junctions 24 and 25 and disruption to our customers New bypasses would be constructed which is likely to be caused when first. Afterwards, our intention is for we are undertaking improvements the bypassed sections of the former of this scale and size. We will A12 road to be passed over to only close the road when we County Council (subject to their really need to for the safety of our agreement), for use by local traffic. road workers and motorists. This is called de-trunking.

On local access roads Where work is to be carried out on local roads, two-way traffic lights/temporary lights might have to be put in place. Traffic management The existing central reserve of the at junctions 19 A12 will be hardened to create additional space for construction Construction of the symmetrical traffic. 24-hour narrow lanes would widening to the junction 19 bridge also operate by moving all four requires the central reserve to be lanes as close to the northbound upgraded.

Junction 24

The construction of this new junction is key to the scheme, as the junction slip roads will be used to divert A12 traffic while the new underpass structure is constructed. Weekend/possible night closures will be required to join the old and the new sections at junction 24. Temporary barriers and lower speed limits with speed cameras will be in place in this section.
