Breakdown of diversions and closures of A720 using B701: EIR release

Information requested

I am seeking details of closures or diversions of the A720 Edinburgh City Bypass that have used the B701 through Colinton Village in the last ten full calendar years (2010-2020) and during 2021 so far.

1. Planned Closures (i.e. diversions):

The number, duration, reason for and time of day of  (e.g. morning, afternoon, night) planned diversions:

a. Westbound only (from at least Dreghorn to Hermiston Gait).

b. Eastbound only (from Hermiston Gait to at least Dreghorn – note this should NOT include any diversions between Hermiston Gait and Baberton that did not divert traffic through Colinton Village).

c. Both directions (as per above but simultaneous Eastbound & Westbound diversions).

2. Unplanned closures: 

As per above, but due to incidents or unexpected/unplanned issues:

a. Westbound only (from at least Dreghorn to Hermiston Gait).

b. Eastbound only (from Hermiston Gait to least Dreghorn – note this should NOT include any diversions between Hermiston Gait and Baberton that did not divert traffic through Colinton Village).

c. Both directions (as per above but simultaneous Eastbound & Westbound diversions). 

3. Costs: 

The approximate costs of implementing:

a. A planned diversion. 

b. An unplanned diverson.

4. Risk Assessment:

a. A copy of the latest Risk Assessment for the diversionary route showing how the route is suitable and safe for pedestrians, cyclists, road users and diverted traffic.

b.  Anticipated traffic volumes of a closure: Eastbound, Westbound, both directions (morning, afternoon or evening).

c. Confirmation as to whether the route is risk assessed for each closure or more generically?

d. Confirmation the risk assessment includes an assessment of emissions effect on local populations.

5. A720 Traffic levels:

a. An overview of the traffic volumes in both directions using the A720 between Hermiston Gait and Dreghorn between 2010 and 2021. If this is not possible, please provide volumes on the whole A720 or similar sections (e.g. Hermiston Gait to Sheriffhall).
