A120 bypass (Little Hadham) and flood alleviation scheme

We're creating a bypass of Little Hadham, running to the north of the village between 2 new roundabouts (Tilekiln and Hadham Park).

We're also looking to reduce the risk of flooding from the River Ash, Albury Tributary and Lloyd Taylor Drain in Little Hadham and Hadham Ford. We'll build 2 dams and divert 1 stream/river (watercourse).

Construction started in July 2019 and will take about 18 months.

Road closures and diversion routes

There are no road closures planned at the moment.


Stay up to date with these roadworks



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.
