Route

The A78 in Largs
Main Article: A78/Route

The A78 is a major road that runs between Greenock and Monkton via Irvine. Hugging close to the Firth of Clyde it is a road of two halves: the northern section is mostly unimproved, passing though such settlements as Largs and Inverkip, while the southern half is a high-standard D2 and D3 dual-carriageway connecting Ardrossan and Irvine to Ayr. The A78 is one of just sixteen F99 routes that have the unusual distinction of maintaining green-signage throughout their entire length. The others are the A12, A14, A16, A17, A22, A42, A43, A45, A53, A55, A75, A83, A84, A86, and A87.

History

Main Article: A78 history

The A78 has had many improvements over the years. The biggest change was a rerouting of the northern end of the road in 1985, away from its original terminal in Gourock to Greenock. Most of the improvements though are on the southern section of the road starting from the Three Towns.

Notable locations and improvements

Bankfoot Roundabout

Main Article: Bankfoot Roundabout

Bankfoot Roundabout is where the A78 used to TOTSO before the 1985 rerouteing. Originally a T-junction and later a D2 T-junction, in 2005 it was upgraded to a roundabout and made the junction far safer.

Rothesay Ferry

Main Article: Rothesay Ferry

The Rothesay ferry is the southern Ferry for the Isle of Bute. It is by far the busier of the two as it docks by Wemyss Bay railway Station. The crossing takes 35 minutes.

Flood Gates

Main Article: A78/Flood Gates

Two sections of the A78 between Skelmorlie and Largs are controlled by flood gates as and when required. The gates do not prevent flooding, they prevent access to flooded sections of the road at the last points where diversions are available. However, the diversion routes use fairly narrow roads and are not suitable for large vehicles.

Cumbrae Ferry
