Travellers are being warned to expect delays from this weekend as essential repairs are carried out on an M9 bridge.
The structural work will be done on the M9 River Almond Bridge over the B800 starting on Friday (May 27) at 10am and will last until midnight on Sunday the following week (June 5).
The B800 road which runs under the motorway bridge will be closed, with signed diversions in place, and a free replacement shuttle bus service will be in operation for local access for the duration of the works.
The B800 will re-open to traffic in a single lane with traffic signal controlled shuttle working from midnight on June 5, with the B800 fully re-opened to two-way traffic by midnight on Saturday, June 18.
Single lane restrictions on the B800 will be lifted for Kirkliston gala day on Saturday, June 11, but will be restored on Sunday, June 12 until completion of the works.
Pedestrian access will be possible through the works via a designated footpath or under escort during periods when critical operations are taking place.
The works will entail concrete and structural steel repairs of the structure and the installation of new expansion joints.
Traffic will be diverted via the B9080 to Winchburgh, the B8020 to Broxburn and the A899 to A89 to Newbridge.
Lochend Road will be restricted to one-way travel Southbound (except for cyclists) between Hallyards Road Junction and the access to the sewage works. A weight restriction on vehicles of 7.5 tonnes or over will be applied for the whole length of Lochend Road, in both directions, other than for local access.
The main shuttle bus service will run every 30 minutes between Winchburgh, Kirkliston Cross and Ferrymuir Retail Park to connect with the normal bus services and will replace the LRT, First Bus and Stagecoach services which normally operate on this route through Kirkliston.
As a result, roads contractor Amey is warning there may be a short wait for connections and is advising commuters to plan journeys accordingly.
The existing First Bus services 21B, 22A and 38 will also provide free travel between Kirkliston, Winchburgh and Ferrymuir Retail Park to connect with the normal bus services.
A free shuttle minibus service will be in operation from 6am every 15 minutes until 11.20pm following a circular route through Kirkliston from Gateside and Kirklands Park.
The designated Pick Up and Set Down spots will be the existing bus stops within Kirkliston.
Amey say the diversion route will add approximately 30 minutes to journey times.
