A77 Overnight closures Planned For Expansion Joint Replacements

Amey, on behalf of Transport Scotland as part of the Network Management Contract for the South-West Trunk Road Unit, are undertaking essential expansion joint replacements across various structures on the A77 from Monday 12th July until Saturday 14th August 2021. Work will take place between the hours of 9pm and 6am, each night.

This scheme, with a value of £135,000, will benefit vehicles using this route each day, by reducing the need for more extensive maintenance in the future.


Works are being undertaken across five structures within the vicinity of Bellfield Interchange near Kilmarnock. Closures will be required with signed diversion routes in operation. The programme is as follows:


  1. Monday 12th July until Friday 16th July 2021 – Closure of Bellfield IC Bridge (South structure): Traffic will be diverted via the A77 Southbound on-slip road to join the A77 Southbound mainline. Traffic will then take the A77 Southbound off-slip to Tarbolton Road, turn right at the roundabout onto the B730, turn right at the following roundabout, and then turn left to join the A77 Northbound mainline. Diversion will end once traffic takes the A77 Northbound off-slip towards Bellfield Interchange.

  2. Monday 19th July until Friday 23rd July 2021 - Closure of Bellfield IC Bridge (North structure): Traffic will be diverted via the A77 Northbound on-slip road to join the A77 Northbound mainline. Traffic will then use the A77 Northbound off-slip road towards Grassyards Road and turn right onto Grassyards Road. From here, traffic will turn right onto the B7082 and will take the second exit at the roundabout to join the A77 Southbound mainline. Diversion will end once traffic takes the A77 southbound off-slip road towards Bellfield Interchange.

  3. Monday 26th July until Friday 30th July 2021 – Closure of A77 Northbound On-Slip from Bellfield IC: Traffic will be diverted via the A77 southbound on-slip road to join the A77 Southbound mainline. Traffic will then take the A77 Southbound off-slip to Tarbolton Road, turn right at the roundabout onto the B730, turn right at the following roundabout, and then turn left to join the A77 Northbound mainline where the diversion ends.

  4. Monday 2nd August until Wednesday 4th August 2021 – Closure of A77 Southbound Off-Slip towards Bellfield IC: Traffic will continue on A77 Southbound mainline and take the A77 Southbound off-slip to Tarbolton road. Traffic will turn right at the roundabout onto B730, right turn at the following roundabout and then turn left to join A77 Northbound mainline. Diversion ends when traffic takes the A77 Northbound off-slip towards Bellfield Interchange.

  5. Monday 9th August until Saturday 14th August 2021: A77 Southbound diversions (9th-11th Aug) – Closure of A77 Southbound mainline beneath Bellfield IC: A77 Southbound traffic to use A77 Southbound off-slip towards Bellfield Interchange. Traffic to then take 3rd exit on to A77 Southbound on-slip and re-join A77 Southbound where diversion ends. A77 Northbound diversions (12th/13th Aug) – Closure of A77 Northbound mainline beneath Bellfield IC: A77 Northbound traffic to use A77 Northbound off-slip towards Bellfield Interchange. Traffic to then take 3rd exit onto A77 Northbound on-slip and re-join A77 Northbound where diversion ends.

Our operatives will follow strict physical distancing and hygiene protocols throughout the programme, in line with the Scottish Government’s COVID-19 guidance.
