A120 bypass (Little Hadham) and flood alleviation scheme

We're building a bypass of Little Hadham to reduce traffic through the village.

We're also looking to reduce flooding in Little Hadham and Hadham Ford. We'll build 2 dams and divert 1 river/stream (watercourse).

We began construction this summer and plan to finish in 2020. Currently, we're excavating large amounts of earth and installing piles in the ground which will stop water seeping under the new road.

Road closures and diversion routes

Roadworks and closures are scheduled at these locations:

A120 Standon Road (Tilekiln Farm)

Fri 8 Nov (10pm) – Sun 10 Nov (5am) – weekend closure.

Fri 22 Nov (10pm) – Sun 25 Nov (5am) – weekend closure.

This part of the works is to construct the Tilekiln Roundabout.

A120 Hadham Road (Hadham Park)

Fri 1 Nov (10pm) – Mon 4 Nov (5am) – weekend closure.

Fri 15 Nov (10pm) – Sun 18 Nov (5am) – weekend closure.

Fri 29 Nov (10pm) – Mon 2 Dec (5am) – weekend closure.

This is part of the works is to start construction of the new Hadham Park Roundabout.

The Ford

Temporary traffic lights to allow for the diversion of utility services and construction of a new culvert (a small tunnel) which will allow water to flow underneath the road.

On occasion we'll need to close The Ford to carry out work. We'll put up signs for this diversion route – The Ford closure diversion route map.


Albury Road

Temporary parking restrictions are needed along Albury Road so we can bring bridge beams to site.

Mon 7 Oct and Mon 14 Oct – keep Albury Road clear in the mornings. We'll put out 'no parking' cones in advance.

Fri 25 Oct (8pm) Mon 28 Oct (6am) – weekend closure to install the bridge beams.

Fri 1 Nov (8pm) – Mon 4 Nov (6am) – we might need to close Albury Road this weekend too, only if we've been unable to complete the work over the previous weekend.

Upwick Green

This will be a full road closure from the junction of Albury Road for 400 metres. It's so we can carry out reconstruction works to the road, due to a change in levels required to stop the road flooding in future.

For the safety of footpath users, we'll close all footpaths at the point they cross the construction site.

We've put up notices on site to warn people that the paths are closed ahead.

We'll, of course, re-open the footpaths and bridleways once work is complete.

Some footpaths will be permanently diverted over short distances to take people to safe crossing points of the new road.


Steps in this project

Step 5: Construction

We have funding approval from the Department for Transport.

We have appointed a contractor, GRAHAM, as our contractor to build the bypass.

Step 4: Getting permission

Step 3: Developing the scheme

Once funding was agreed for the project, we progressed the design. We shared this at the pre-planning consultation.

Based on your feedback we made a number of changes – see the A120 pre-planning application update.

Step 2: Seeking funding

The construction cost for the project is expected to be about £30 million.

The biggest bit of funding will come from the Hertfordshire Local Enterprise Partnership (LEP) which has been granted approximately £27.4 million by the Government.

You could build a flood alleviation scheme without the bypass, but this would need a lot more funding.

The Environment Agency will be contributing towards the flood alleviation scheme.

Step 1: Early options

In 2007 we assessed the traffic situation in Little Hadham and decided a bypass would be the best solution to reduce congestion in the area.

We drew up plans for a number of routes and chose what we considered to be the best option based on safety, effectiveness and cost.

A consultation was held to find out what you thought of the early plans. The Environment Agency came along to the consultation to show how we could reduce flooding with each route too.
