Road Bridge Maintenance - Inspections and Carrying Capacity - Find a freedom of information request

Defining a “road bridge” as a structure with a span of 1.5m or more providing public highway passage for motor vehicles over an obstacle such as a watercourse, railway, road or valley, please provide the following information for all road bridges for which you own as highway authority, including those which are jointly owned with another authority, but for which you are the lead authority:

4. For the last financial year (2018/19) how many Structural Reviews and/or BD21 assessments have been conducted?

5. How many sub-standard (in terms of capacity) and/or weight restricted bridges do you have?

6. Of these, how many do you intend to return to full load carrying capacity in the next 5 years?

7. How many bridges would you return to full load carrying capacity if you had no resource restrictions?

8.

(i) How many of your bridges require post tensioned special inspections (PTSIs)?
(ii) How many of those have had PTSIs within the last 18 years?
(iii) Of those that have not had a PTSI, how many require/are due one?

9. In monetary terms, what is the current Depreciation (i.e. difference between your GRC and DRC as declared for your WGA return for 2018/19)?

10. Have you calculated your back log (or workbank) for bridges? What is the calculated value of your backlog of road bridges, or your best estimate if a calculated value is not available?

11.

(i) What is the annual revenue works budget for maintaining your bridge stock?
(ii) What is the annual capital works budget for maintaining your bridge stock?
(iii) What total budget would you estimate is required to maintain the bridge stock at its current level (standstill budget)?
