The 'temporary' 50mph speed limit on Perth's Friarton Bridge, initially imposed in July 2024, remains in effect two years later as detailed engineering assessments continue following reports of spalling concrete.
Bridge Background and Initial Incident
The Friarton Bridge, carrying the M90 over the River Tay, was the longest span steel girder bridge in the UK when built and the first to use a composite lightweight concrete deck. Construction began in 1975 and it opened in summer 1978.
In July 2024, Transport Scotland's operating company for the North East Trunk Road Unit, Amey, inspected the bridge after reports of spalling concrete. Further surveys led to the installation of temporary traffic management, including a 50mph limit effective from July 30, 2024.
Current Status and Safety Measures
An Amey spokesperson stated: "The temporary traffic management and speed limit were installed on Friarton Bridge to ensure the safety of the travelling public following reports of spalling concrete from the structure. The reduced speed limit is required due to the temporary safety barrier installed on the bridge. Detailed engineering assessments and design work remain ongoing, and we will provide further updates when information is available."
The speed restriction is necessary because the temporary safety barrier is in place, and the limit is intended to protect motorists.
Local Reaction
Carse of Gowrie councillor Baillie Alasdair Bailey expressed frustration: "With the realisation last week that signs haven't been updated for the year-old cross tay link road, and now confirmation that there is still no plan to fix the barriers on the Friarton Bridge which is a critical piece of infrastructure for the region. People here tell me they feel left behind and forgotten by Transport Scotland and their operating company AMEY."
The ongoing situation highlights concerns over infrastructure maintenance and communication with the public.
