Island Roads have removed the traffic lights from Hope Hill in Shanklin and reinstated the carriageway.
Traffic has recently been controlled by temporary lights for safety reasons after a void appeared beneath the road surface.
This void has been linked to underground pipework and investigations will continue into what is causing the underlying issue.
Steve Ashman, Island Roads service director, said:
“These investigations have so far proved inconclusive and are ongoing but in the meantime we have taken the decision to fill in the void and reinstate the road
“This means the busy road serving the Esplanade is now fully open in time for the weekend and in advance of the forthcoming Bank Holiday.”
Steve said it may be necessary to conduct further minor work while investigations continue – such as lifting manhole covers and excavating small trial holes - but this would only be short-term.
He added:
“If further, more significant, work is required then this will be planned for after the tourism season.
“We apologise for the recent inconvenience while the lights have been in place but it is important that we controlled traffic until we understood more about what had caused the void to appear. While more investigation is required, we are satisfied that the road can now be made safe for use and we will of course keep the local community informed of any future work in this area.”
