A9 Dualling: Pitlochry to Killiecrankie

The Scope involves the design, construction, completion and landscape maintenance of the proposed A9 Dualling: Pitlochry to Killiecrankie project.

The project will be the fifth section of the A9 Dualling Programme to be constructed, which aims to improve the operational performance of the A9, improve safety for motorised and non-motorised users, facilitate active travel within the corridor, and improve integration with Public Transport Facilities. The objectives are to be met whilst avoiding and/or reducing environmental impacts, enhancing the environment and improving sustainability where possible.

The Project involves the dualling of approximately four miles (6.4km) of existing single carriageway. This consists of approximately 4km of online widening and approximately 2km of offline construction. The project commences approximately 1km south of the existing Tummel underbridge and ends at the existing dual carriageway at the Pass of Killiecrankie. This section of the A9 is located in a rural area within close proximity to a number of designated environmental sites, such as the River Tay Special Area of Conservation (SAC) including the River Tummel and Loch Faskally, which are crossed by the existing A9.

In particular, the project involves, but is not limited to:

- Widening of existing A9 single carriageway to Dual 2 lane All-purpose roads Sub-category c (D2APc) standard, in accordance with ‘CD 109 Highway Link Design’ within the UK Design Manual for Roads and Bridges.

- Upgrades to the existing Pitlochry South Junction and Pitlochry North at-grade Junction to fully grade separated junctions.

- Construction of two left-in left-out junctions at C452 Foss Road and C452 Clunie-Foss Road.

- Upgrade to side roads including resurfacing or realignment and other improvements.

- Construction of access roads to rural properties and businesses, including a further two left-in/left-out junctions onto the A9 with one at Pitlochry Estate and one at Kennel Cottage.

- A Type-A Lay-by, which will provide physical segregation between the main carriageway and the lay-by, located on the northbound side of the A9, near the Tummel underbridge.

- Demolition and replacement of three existing underbridges; Clunie-Foss Bridge, Foss Road Bridge and Craighulan Bridge.

- A new underbridge at the River Tummel (Tummel underbridge) to accommodate the proposed A9 northbound carriageway.

- A new underbridge at Loch Faskally (Clunie underbridge) to accommodate the proposed A9 southbound carriageway.

- An extension of one existing rail underbridge and one new rail underbridge.

- Provision of five other new underbridges/underpasses, six new retaining walls and 15 culverts.

- Bearing replacement and concrete repairs to piers at the existing Tummel underbridge.

- Earthworks, including excavation of rock.

- Replacement and/or upgrade to a number of existing structures including culverts and Sustainable Drainage Systems (SuDS) developed in consultation with Scottish Environment Protection Agency (SEPA).

- Provision of traffic management, road restraint systems, accommodation works, service diversions, fencing, signage, landscaping and environmental mitigation.
