In late 2016, work started on changes to the St. Johnstone Interchange in Perth, where the A85 meets the A9 Perth Bypass. This project includes the construction of a new road leading northwest to meet the western end of the Inveralmond Industrial Estate, and so provide an alternative route, hopefully reducing traffic on the A9. A new bridge over the River Almond to provide access to the proposed Bertha Park Development, a large new suburb to the northwest of Perth city, was built as part of phase one, and appears to be numbered as the B9993. There is also a plan to continue this new road to the north of the industrial estate to rejoin the A9 at a new junction to the north of the existing Inveralmond Roundabout.
This second part of the route is the Springfield Link Road which will start at the new roundabout at Bertha Park to the north of the River Almond. The road then runs north east, loosely following the pylons, before turning east to meet the new junction on the A9. This is proposed to be a folded dumbbell interchange, with the sliproads curled to the south of the junction. Ultimately, the new road is planned to continue east as the Cross Tay Link Road, connecting to the A93 and A94 with a new bridge over the Tay.
The Springfield Link Road is phase 3 of the Perth Transport Futures project and as such is unlikely to start until the Cross Tay Link Road is completed.
