|Route outline (key)|
The B3027 still "exists" in part on the ground between California Cross and Modbury on signage and a route confirmation sign, though it is not shown on maps as it was decommissioned in 1991.
The road is signed as the main route to Dartmouth from Modbury, and the preferred route to Modbury from Short Cross, though it is only 5-10 minutes shorter that taking the A379; however, it does benefit from having fewer gradients.
From Modbury the B3027 left the A379 from the bottom of the steep hill, where Dartmouth is 15 miles away along "Old Dartmouth Road". Traffic from Plymouth can benefit from taking the signed route at the top of the hill round the back of Modbury thus avoiding the steep gradients. The road is S2 or S1 through out and there is evidence that the road has been narrowed in the burn off centre lines. There are a number of campsites served around California Cross that provide most of the traffic apart from the locals taking short cuts.
At California Cross the road briefly multiplexes with the B3196. Heading to Dartmouth the B3207 TOTSOs right after the petrol station, whilst in the reverse direction the B3196 TOTSOs. After California Cross the road is mainly S1 as it makes its steep decent down to Gara Bridge. The hump-back bridge here has a 10T weight and a 25ft length restriction, probably the cause of the downgrading.
The other side of the river the road becomes spookily well maintained and well built in comparison to the rest; the steep incline back up is S2 though out until the village of Morleigh is reached where it becomes S1 and the speed limit is cut to 20mph. It meets here the popular back route to Dittisham and Avonwick before TOTSOing off towards the village of Halwell. This incurs another steep decline and incline, though this can be avoided by taking the flatter road out to Short Cross, however both ways will deposit you onto the A381.
Following a multiplex to the left the rest of the route of the old B3207 is now the A3122 to Dartmouth; this was the only part of the road deemed worthy of continued classification in 1991. That road ends on the A379 to the west of town but it originally zigzagged along Victoria Road to meet the A379 by the river; this became part of a rerouted A379 after World War II and is now largely bypassed. The present A379 to the south of here as far as the junction with the B3205 was also part of the B3207 and was taken over at the same time. This was originally unclassified but became the B3206 in the 1920s and then a spur of the B3207 in 1935.
