A120 Little Hadham Bypass and Flood Alleviation Scheme

The project

A120 team

A significant infrastructure project for the county: once complete, the new 3.9km bypass to the north of Little Hadham will alleviate congestion caused by the Little Hadham traffic lights and provide more reliable journey times. Hertfordshire County Council have worked in partnership with the Environment Agency to develop the scheme to include flood alleviation measures. New road embankments across the River Ash and Albury tributary will act as flood storage dams to reduce flood risk to the village and other nearby communities. The scheme will improve air quality in Little Hadham and also ultimately benefit the county’s economy, with more reliable transport links to Stansted Airport alongside other long-term advantages for Hertfordshire.

Across these pages you can learn about the archaeological excavations and discoveries at the A120 Little Hadham Bypass and Flood Alleviation Scheme. Details are given about the background to the project and the investigations that took place prior to the main excavations.  These excavations have helped us understand a great deal more about the communities that lived and farmed the landscape around Little Hadham 2,000 years ago.

Meet the team

A120 archaeologists

The A120 Little Hadham Bypass and Flood Alleviation scheme is primarily supported by Local Growth Fund investment from Hertfordshire Local Enterprise Partnership (LEP), with additional investment secured by the LEP from the Department for Transport, as part of a wider funding package with Hertfordshire County Council and the Environment Agency.

An archaeological project of this scale and complexity required the involvement of a diverse set of skills and expertise. During the excavation there was up to as many as 50 archaeologists working on site. Since the site work was finished further archaeologists with a range of skills have been analysing the finds too. At the link below you can see videos from our team, giving a unique insight into their role and work on the project. Of course, the archaeological project didn’t take place in isolation, it was just one small part of a much larger project to construct the new road and flood alleviation scheme. And special mention must go to the designers, engineers and construction workers that formed part of one big team to make this project happen.
