A90 resurfacing and bridge/flyover measurements: EIR release

Information requested

Details of the number of times the road (the A90) under Low Carse flyover has been re-surfaced (or any work done to repair the road surface), in both directions, during last 10 years and dates of same works/repairs. 

Details of the number of times the height of the flyover/bridge has been measured (date, method used to measure, confirmation of where the measurement is recorded and whether the measurement prompted any change of signage) and what those recorded measurements were during the last 10 years.

Response

As the information you have requested is ‘environmental information’ for the purposes of the Environmental Information (Scotland) Regulations 2004 (EIRs), we are required to deal with your request under those Regulations. We are applying the exemption at section 39(2) of the Freedom of Information (Scotland) Act 2002 (FOISA), so that we do not also have to deal with your request under FOISA.

This exemption is subject to the ‘public interest test’. Therefore, taking account of all the circumstances of this case, we have considered if the public interest in disclosing the information outweighs the public interest in applying the exemption. We have found that, on balance, the public interest lies in favour of upholding the exemption, because there is no public interest in dealing with the same request under two different regimes.

This is essentially a technical point and has no material effect on the outcome of your request.

1. The number of times the road (the A90) under Low Carse flyover has been resurfaced (or any work done to repair the road surface) in both directions?
Resurfacing/road repairs have been carried out 3 times under the bridge within this period, dates are shown in the following table –

26/11/2013	27/11/2013

2. Number of times the height of the flyover/bridge has been measured?
In the last 10 years the available height (headroom) under the bridge has been measured three times.

3. Confirmation of where the measurement is recorded.
The minimum headroom measurement is recorded within Transport Scotland’s Asset Management Performance System.

4. Did the measurement prompt any change of signage?
No, this did not result in a change of signage.

5. What were the recorded measurements (and dates and methods used to measure)?
1. The minimum headroom recorded at the Principal Inspection of 16/08/2013 was 5.12m and this was measured using laser distometer and was located above the northbound carriageway.

2. At the subsequent Principal Inspection of 17/10/2019 the minimum headroom was 5.13m and this was again measured using laser distometer.

3. On 28/03/23, immediately following the most recent bridge strike, headroom measurements were taken using laser distometer above the southbound carriageway (side of bridge strike) and the minimum of the readings was 5.265m.
