In 2011, Transport Scotland envisioned a plan to upgrade the remaining 90 miles (145 km) of the A9, a trunk road in Scotland, between Perth and Inverness from a single carriageway to a dual carriageway. According to this plan, the road will be widened from one to two lanes per direction (two to four lanes total), and will also have a central reservation. It also means there will be an increase in speed for cars and motorcycles from 60 mph to 70 mph (96 km/h to 112 km/h).
A dual carriageway allows drivers to overtake safely as they do not have to meet oncoming traffic and the crash barriers on the central reservation will greatly reduce the number of head-on collisions. As most of the A9 is currently a single carriageway, drivers will possibly have to overtake heavy goods vehicles (HGVs) and other slow-moving vehicles as they are limited to 50 mph (80 km/h), 10 mph (16 km/h) lower than the speed limit for cars and motorcycles. The project started in September 2015 with a planned completion date of 2025, but it will not be finished on time due to delays.
