Improvement work is due to begin at a hospital and parking will become limited.
The project at Worthing Hospital is in preparation for a new urgent treatment centre (UTC) and a same-day emergency care unit.
The UTC is being moved from its current location opposite the X-ray department to inside the emergency department.
A same-day emergency care unit will be built on the site of the old UTC, with an expanded waiting area and a new courtyard extension including ten consultation rooms and utility rooms.
Heat pumps will be installed to provide a more sustainable heat source, as part of Worthing Borough Council’s partnership with heat network investor Hemiko to bring climate-friendly heating to every building in the town by 2050.
The pumps will save on fuel and carbon as well as reducing costs due to less maintenance visits, fuel prices and insurance inspections.
However, University Hospitals Sussex NHS Foundation Trust has warned that visitors to the hospital may experience limited parking.

Between August 19 and October 17, an area of the main public car park will be closed for works to take place.
If the car park becomes full, visitors will be redirected to the nearest offsite public car park by traffic officers and signs.
Pedestrians accessing the hospital from the main entrance will also have to take a longer route round the edge of the car park to access the south wing entrance.
Disabled parking will remain in the main car park.
A spokesman for the trust said: “We have made every effort to minimise disruption during this period and apologise for any inconvenience caused while we improve our hospital.
“We will continue to monitor the impact on visitors and make amendments if required.”
Stephen Mardlin, Worthing hospital director, said: “I am really pleased to see these projects in action to enhance our ability to provide efficient patient care with the expansion of our UTC and by playing an important part in improving the health of our patients, the environment and the wider community with the heat network.”
