The Highways Agency is to spend £9.5m on improvements and safety works to the M62 around Warrington, Cheshire.
The six-month project will introduce new concrete barriers to the central reservation, as well as "tiger tails" added to the end of link roads on the M6, providing extra entry lanes onto the carriageway, in a bid to increase driver safety.
The improvements, due to start on 17 September and scheduled for completion in March next year, are between Junction 9 of the motorway at Winwick and Junction 11 at Birchwood.
Matt Sweeting, Highways Agency regional asset delivery manager, says: "This is a significant investment which will improve safety, reduce maintenance visits and associated disruption for drivers."
