The A814 road in Scotland (known for part of its length as the Clydeside Expressway) is a major arterial route within Glasgow, connecting the city centre to the west end.

After passing the SEC Centre / SSE Hydro on one side and residential Kelvinhaugh and Yorkhill on the other (two footbridges provide pedestrian access at what is a very busy and fast-moving section), an atypical junction added in the early 21st century just prior to the River Kelvin provides access from the Expressway to eastern Partick and the Riverside Museum from the westbound direction, with eastbound entry/exit points further on at Glasgow Harbour where the main carriageway is in a cutting.

Now out of the city, it feeds the A82 / A898 (Erskine Bridge interchange) at Old Kilpatrick then merges with the A82 for a short distance as a dual carriageway before recovering its designation through the town centre of Dumbarton (as Glasgow Road and Cardross Road), over the River Leven and past Cardross, directly next to the Firth of Clyde through Helensburgh and alongside the Gare Loch past Faslane naval base.

The Expressway has a number of unique grade separated junctions designed to enable efficient movement of traffic whilst minimising land take.

The design of this junction created a challenge as it was a requirement that it should be completely free flowing whilst also not taking any land from the nearby Victoria Park.
