Traffic delays are expected in and around Eastern Road, Brighton, as workers run a new power supply into the Royal Sussex County Hospital.
The work was due to start yesterday (Saturday 30 May) and continue today (Sunday 31 May).
The same arrangements will apply on the weekend of Saturday 13 and Sunday 14 June.
Eastern Road will be reduced to a single lane while UK Power Networks runs a new electrical supply into the hospital as part of the £480 million modernisation.
A section of Eastern Road, next to the south west corner of the hospital, will be reduced to a single lane between 9am and 5pm.
Five-way temporary traffic lights are being set up across the extended junction made up by Eastern Road, Abbey Road, Upper Abbey Road and Bellevue Gardens.
The pedestrian crossing in front of the hospital will be suspended and a temporary one put in place further west, outside the hospital’s main Outpatient Department.
The bus stops on either side of Eastern Road, towards the west end of the hospital site, will be moved further east temporarily. Buses that would normally stop outside the main Outpatient Building will use the Sussex Eye Hospital stop instead.
The power supply will be used in work to modernise the hospital, including supplying electricity to the new modular building at the front of the hospital site. It will house clinical services and clear space for the first phase of the “3Ts” project.
