Contractors are being invited to bid for the construction of a new junction on the M9 motorway as part of the Forth Replacement Crossing.
Close scrutiny of public spending had cast doubts over the £2bn bridge, but it recently passed its first hurdle in the Scottish Parliament, with MSPs backing the plans by 113 votes to 3.
The £65m M9 road junction scheme will be let as a design and build contract, comprising: the upgrading of Junction 1a on the M9 to provide west facing connections between the M9 and the M9 Spur; improvements to the exisiting east facing slip roads; and widening of the existing M9 between Junction 1a and the River Almond crossing (towards the Newbridge junction).
The upgrade will require the construction of a new overbridge adjacent to the existing overbridge on the M9, widening of the exisiting bridge over Overton Road, and widening of the existing B9080 underbridge on the M9 Spur.
The exisiting Swine Burn will be diverted, requiring an additional culvert to be placed under the proposed east bound off slip, together with other associated culvert extensions.
Included within the contract will be the provision of an Intelligent Transport System (ITS) and associated infrastructure and the installation. The infrastructure will include overhead gantries, maintenance hardstandings and carriageway traffic detectors. The ITS will be installed between Junction 2 (Philipstoun) and Junction 1 (Newbridge) on the M9 and along the length of the M9 Spur.
The construction programme is scheduled to start in July 2011, completing in December 2013.
The deadline for expressions of interest is 23 July.
