20mph speed limit between Government House and Third Avenue
Further work on the Glencrutchery Road and Governor's Dip areas of Douglas is to be carried out overnight.
The Department of Infrastructure says the roads will stay open as more signage is installed and line painting takes place.
There will also be a 20mph speed limit introduced between the Gate House at Government House and Third Avenue.
Alterations are set to accommodate Douglas promenade's current northbound one-way system.
The temporary measures are to stay in place until the prom returns to its two-way traffic flow.
Work is to start from 10pm until 6am tomorrow morning.
