A27 Arundel bypass
As the main road serving the south coast, the A27 is a crucial route through the south east. However, as it passes through Arundel it operates well over capacity and causes disruption and severe congestion. Highways England is therefore developing options for how the route could be improved.
By making changes to the A27 at Arundel we’re aiming to:
- Improve safety
- Increase the capacity of the road
- Reduce congestion and travel time
- Have as little impact as possible on the environment
- Protect and enhance the quality of the surrounding environment through high quality design
- Respect the South Downs National Park and its special qualities in our decision-making
We need this scheme because the A27 through Arundel causes a daily build up of traffic that costs commuters, businesses, communities and visitors valuable time and money. In fact, the congestions costs businesses millions of pounds a year. The road also cuts off communities and makes every day trips longer and more difficult.
Our surveying teams are working to gather as much information as possible about the site of the proposed A27 Arundel bypass. With landowners’ permission, and working with the relevant local authorities and licensing bodies, our teams will be out and about on site carrying out surveys. You might notice them conducting this vital work, so we’re taking a closer look below to explain what data is being gathered and why it’s so important for our design team.
Archaeological trial trenching
We’re about to begin archaeological investigations, which means we’ll be looking for - and recording - any archaeological findings. You may see some of our archaeology team starting the surveys in September and continuing over the coming months. Whether it’s prehistoric animal bones, stone-age hand tools, medieval farm equipment or Victorian military remains, we’ll carefully record everything we find and produce a report for the public record.
We are working with the archaeology team at West Sussex County Council to plan this work. The results of these surveys will provide our road design team with valuable evidence about the archaeology of the site, allowing us to make sure we’re minimising the impact of the road design on any historical remains we find. We expect most of this archaeology work to take place on weekdays.
Our Arboricultural team of tree specialists look at the areas on site where existing trees might be affected during the construction of the proposed road. They visit the site and examine the trees, recording information about their location, size, condition, quality and species. Our tree specialists work in small teams and their surveys are not invasive. The tree survey data will be used to inform the design team about trees on site, including their required canopy and root protection zones. Although the proposed route of the road does not pass through any ancient woodland at all, there are still many significant trees on the site and the Arboricultural survey will help us to understand how we can design the road to have the smallest possible impact on existing trees in the area and also where would be the best areas to plant new trees.
Our water survey team are working to gather as much information as possible about surface water conditions at the site of the proposed road – like the condition of rivers and streams, and information about flood plains. This ‘baseline data’ will be gathered by small teams of water surveyors over the coming weeks. You might notice people with bottles gathering water samples from specific points in the streams and rivers on site. This is to make sure we understand as much as possible about the current water quality so that our design team can put in place the best type of drainage measures to protect it as they develop plans for the road. You might also see people using a hand-held ‘flow meter’ – a device that tells us how fast the water is moving along a water course. All these observations are repeated at different times of year to make sure seasonal changes are taken into account.
Our ecology team work around the clock to gather information about the ecology of the site. This includes information about the wildlife habitats as well as individual species, and they’ll be looking on land, in the watercourses, and up in the air! Ecologists will be on site most weeks, looking for different things depending on the season and the weather conditions. Surveys are ongoing to look for evidence of animals like bats, great crested newts, otters and water voles – protected species that, if discovered, will be carefully considered as we continue designing the road. This might mean for example avoiding valuable habitat where possible, creating new habitats and planning for the careful relocation of animals.
Due to the nature of the work, our ecology teams might be on site at all times of the day and night. Bat surveying, for example, needs to happen at dusk and into the evening to observe bats entering and leaving their roosts.
The information gathered by the ecologists is vital for the design team, enabling them to make informed decisions about areas of valuable habitat on site and also letting them know where extra habitat might need to be created. You can find out more about the work of the ecology team by watching our video from earlier in the project.
