MyProm, contractor and DoI working towards 'tight schedule'
Additional time has been allocated for final surfacing work on Douglas promenade to be completed.
Government says day and night road closure notices include extra time in case the weather is poor.
Auldyn Construction's four-week plan shows the regeneration scheme continuing into October.
MyProm says the contractor, and the Department of Infrastructure, are working hard to minimise disruption whilst working towards a 'tight schedule of works'.
It adds: "As the works reach its finish the contractor is balancing a number of road closures both daytime and night time, in order to get the scheme completed.
"Both the Department of Infrastructure and Auldyn Construction are working hard to minimise disruption to businesses, residents, motorists and pedestrians while working towards a tight schedule of works.
"Final surfacing works are weather dependent so some additional time has been allocated to the road traffic notices. Every endeavour is being made to complete as soon as possible."
