Chepstow's fixture on August 14 has been given the go-ahead, but racing will only be staged on the round course at the Monmouthshire circuit.
Richard Linley, British Horseracing Authority senior inspector of courses, was happy with what he saw following a Wednesday inspection, though the straight course is still not in a fit enough state to stage competitive races.
The original races at Chepstow over five and eight furlongs have been abandoned and three new races have been added to the card.
Jim Allen, racing director at Arena Racing Company, said: "We are pleased with the improvement shown with the turf and delighted to be racing next Thursday.
"We would like to thank the BHA for their assistance in ensuring this fixture can go ahead."
Chepstow's meetings on July 25 and August 6 were transferred to Lingfield due to surface issues involving nematodes, which are microscopic organisms that feed on the roots of plants.
