Work to replace the A41’s battered road surface in Tring will begin next week.
Starting on Wednesday, March 5 there will be full road closures from 8pm to 5am between the A4251 London Road junction to the B488 Icknield Way junction.
The £320,000 project is expected to take 10 nights to complete, and alternative routes will be signposted.
Herts County Council’s cabinet member for highways Terry Douris said: “These works form part of our ongoing commitment to maintain and improve our roads for the benefit of all road users in Hertfordshire.
“We appreciate that this is a major and busy route and understand that these significant resurfacing works are likely to cause disruption and inconvenience to motorists.
“We apologise for this and would ask everyone for their co-operation while the work is in progress.”
