A proposal is going to Lincolnshire County Council’s Highways and Transport Scrutiny Committee meeting on Monday, 11th March centred on improvements to both the Riseholme roundabout and Nettleham roundabout on the A46.
As part of the project, the following improvements will be made to each roundabout:
- Riseholme – adding an extra lane in roundabout itself and constructing an extra entrance and exit lane at all approaches and exits
- Nettleham – extending the length of all of the roundabout’s two lane approaches and exits
In addition, drainage systems at both roundabouts will be rebuilt, new signs and lighting columns installed and sections of the existing road rebuilt to minimise future maintenance.
Lincoln’s northern bypass is one of the county’s most important roads. Not only does it offer a route around the top half of Lincoln, but it’s also a vital section of the Lincolnshire Coastal Highway.
However, at the moment, the Riseholme and Nettleham roundabouts are operating just under full capacity, meaning drivers often face queues – particularly at peak times. And with the number of vehicles using the bypass due to increase over the coming years, this situation will only get worse.
Although many people think dualling the bypass between these roundabouts would be best way of keeping traffic flowing, Lincolnshire County Council’s models show that the real problem is at the approach and exits lanes since that’s where traffic gets bottled up.
Once approved, the authority plan to appoint a contractor later this year with a view to breaking ground during February 2020.
Each roundabout will take about seven months to construct, and, as of now, we intend to build both at the same time to minimise disruption. However, that could change as the scheme develops.
When we start on-site early next year, road users can expect a combination of narrowed lanes, temporary speed reductions and night-time road closures during the works.
This will inevitably cause some disruption, but we will do our absolute best to keep traffic moving while we carry out these much-needed improvements.
The proposed £4.7m scheme will be funded Lincolnshire County Council and the Greater Lincolnshire LEP.
