Plans to improve journey times and increase safety on the A1 between Leeming and Barton, North Yorkshire, by upgrading the dual carriageway to a three-lane motorway, will go on show to the public today.
The Government announced £314million of funding to allow work on the upgrade to start.
The scheme will result in a continuous motorway-standard route from London to Newcastle (including the M1 and A1M). Journey times between Leeming and Barton will also be reduced.
The improvements are predicted to save around 100 lives and prevent around 650 serious casualties.
A public information exhibition will be held at the Bridge House Hotel in Catterick, North Yorkshire, on Friday 15 February (2pm - 8pm) and Saturday 16 February (10am - 4pm).
Construction on the 12-mile project, which is due to open to traffic in 2016/17, is also estimated to generate 750 jobs in the construction industry over the three-year contract.
"The new motorway will bring a range of benefits to the region - from improved safety to reduced journey times. It will directly benefit business users and potentially attract further development and growth."
At the exhibitions, information on access for pedestrians, cyclists and horse riders, and details of the environmental work to be carried out, will also be on available.
Members of the Highways Agency project team will also be on hand to listen to comments and concerns, and answer any questions that people may have.
