From next Monday (May 14) shoppers and tourists will enjoy free parking from midday in a bid to lure trade back to the city following the nerve agent attack back in March.
The five park and ride sites that serve the city will continue to be free.
Wiltshire Council had previously offered free all-day parking in its car parks after shop footfall plummeted.
Wiltshire Council leader Jane Scott said: "We implemented free parking to encourage people to visit the city and to promote it is very much business as usual.
"However, the feedback we have received has highlighted the need to reconsider free parking in the city to ensure that local businesses can benefit from additional visitors and shoppers.
"We have decided to implement a new option while Salisbury continues to recover.
"This initiative is funded by Wiltshire Council and Salisbury City Council, which is a significant investment and it has helped to improve footfall in the city.
"We will continue to do everything we can to assist and support Salisbury through this extraordinary situation."
