A390 roadとは 意味・読み方・使い方

The A390 is a road in Cornwall and Devon, England. It runs from Tavistock to 5 miles (8.0 km) north west of the city of Truro. Starting in Tavistock, it heads south-westwards towards Liskeard, crossing over the River Tamar and into Cornwall, then through Gunnislake and Callington. Immediately before Liskeard, it merges with the A38 north of the town. It diverges from the A38 at Dobwalls, where it then runs in a south-westerly direction to Truro via Lostwithiel, St. Blazey, and St Austell. It then forms a loop, and bypasses Truro City Centre. It then heads north west out of the city, where it forms the main corridor into Truro from the west. It passes the Royal Cornwall Hospital and through the suburb of Threemilestone, before linking up with the A30 road at Chiverton Cross, where the A390 terminates. It forms part of the main route (the Truro to Dobwalls section) from Truro to Plymouth, although after a severe accident in Lostwithiel in 1999 heavy goods vehicles are diverted from it at the top of Edgcumbe Road, Lostwithiel.
