West Sussex County Council will invest £45,000 to replace an obsolete pelican crossing with a new puffin style crossing at The Esplanade in Bognor Regis.
The council said work is required because the existing traffic signals, near Waterloo Square, are reaching the end of their lifespan.
Furthermore, as replacement parts are difficult to source, a new crossing will be installed utilising the latest equipment for improved reliability and energy efficiency.
The new crossing will feature above-ground detectors, which identify when pedestrians are clear of the crossing before reverting back to green for vehicles.
According to the council, this is what makes the solution different to a pelican crossing that relays on a timer.
There will also be tactile cones on the underside of the control box and audible bleepers to help visually impaired pedestrians.
Additionally, LED equipment will improve visibility for road users and keep energy and maintenance costs down.
There will also be an additional pole on the southern footway to improve forward visibility for eastbound traffic.
This will allow an additional traffic signals head to be aligned to improve vehicle visibility at the stop-line and those exiting Waterloo Square.
A West Sussex County Council spokesperson said: “We apologise for any inconvenience caused during the work but please bear in mind this project will lead to long-term improvements.
“If possible, road users are advised to seek alternative routes, particularly during peak periods.”
The council said, subject to severe weather, work is scheduled to start on 22 February and will take about two weeks.
