Work is getting underway to help ease some of the parking and access difficulties at Frimley Park Hospital.
From Monday 13 July, builders will be starting on site to create a new upper deck above an open air visitor car park at the front of the hospital that will add an extra 118 spaces. It is expected to take 18 weeks to complete and cars could be using the new deck from mid November 2015.
Frimley Health NHS Foundation Trust is investing £2.5m to increase the total number of visitors' spaces at Frimley Park by a third to nearly 470.
The extra capacity combined with the on-going work by Surrey County Council to add an extra lane for east bound traffic along Portsmouth Road, will go a long way towards improving access to Frimley Park Hospital and congestion on surrounding roads.
While building continues, up to 300 staff vehicles will be temporarily moved from the Frimley Park Hospital main site to the hospital trust's staff parking facilities in nearby Lyon Way to free up the existing on-site upper deck car park for patients and visitors.
The scheme was unanimously approved by Surrey Heath Borough Council planners in May.
Janet King, director of HR and corporate services at Frimley Health NHS Foundation Trust, said: "We understand the frustration that difficulties with access and parking can cause for patients, visitors and staff at peak times and in recent years we have invested a lot of time and effort in trying to alleviate them.
"We have already invested in offsite parking for hundreds of staff to free up more visitor spaces and expanded our satellite outpatient and diagnostic services at Aldershot, Fleet, Farnham and Bracknell. But having a successful hospital at Frimley with a good reputation has meant that demand for access has continued to grow.
"We don't think the extra capacity will completely solve all the parking and access issues. But, combined with the road widening on Portsmouth Road, we believe it will make a significant contribution towards easing congestion on and around the site."
Each car parking space at Frimley Park is used approximately three times each day, so the extra capacity will allow for about 450 extra vehicles in every 24 hour period.
The upper deck that is being opened to patients and visitors does not have a lift to the ground floor. Therefore visitors who are not able to use the stairs will be directed to continue using the ground level of the car park. Extra parking and security staff will be on site to help visitors park appropriately and to patrol Lyon Way for longer throughout the day to improve safety for staff who work late shifts.
