The new A264 Link Road near Broadbridge Heath will open on Thursday..
Developer Countryside Properties, who opened the new A24 junction at Broadbridge Heath in June, has informed West Sussex County Council the road is ready to use.
The 1km link road cost approximately £4.5m and Countryside has funded it.
It connects the A24 junction to the Newbridge Nursery Roundabout on the A264 Five Oaks Road.
It also provides access to the Wickhurst Green housing development.
John O’Brien, West Sussex County Council Cabinet Member for Highways and Transport, said: “This new road will ease pressure on Broadbridge Heath.
“It will reduce some of the rush hour traffic and allow traffic to get on the A24 easier.
“I think one of the key things when there is a demand for housing is to have appropriate infrastructure in place, which thankfully we have here now.”
The A264 Link Road is part of an infrastructure package designed to cope with 2,000 new homes south of Broadbridge Heath and west of Horsham.
Andrew Carrington, managing director of strategic lands at Countryside, said:
“We are delighted to be opening the A264 link road considerably earlier than our planning obligations require.
“This is great news for the travelling public and local community who’ve been especially patient during these works.”
The County Council will now prioritise the remaining highway improvements to come from the funding secured in association with these developments.
- Traffic calming schemes for Broadbridge Heath and Warnham;
- Further junction improvements on the A24.
