West Sussex Highways is investing £3m in the 2017/18 financial year - on top of the £2m spent last year – across six towns in the county.
The county council say the programme is designed to improve pavements and footways most used by vulnerable residents, both old and young, to protect people from slips, trips and falls.
Further locations will be announced later this year.
Roads included are as follows:
• Florence Road
• Kingsham Road
• Spitalfield Lane
• College Lane
• Summersdale Road
• Winterbourne Road
• Parchment Street to Orchard Street
• Sherborne Road
West Sussex County Council’s Cabinet Member for Highways and Transport, Bob Lanzer, said: “We prioritised pavements and footways which serve clinics, hospitals, areas with high footfall and schools.
“This is after many months of inspections and assessments to decide which streets get included in the programme for a second year.
“We made a great start last year and are keen to build on that work.”
The programme is subject to change, dependent on weather and other factors.
