[2] The bridge connects West Dunbartonshire with Renfrewshire and can be used by all types of motor vehicles, cyclists and pedestrians.

A small part of Kilpatrick railway station is situated underneath the bridge at the north side.

The road surface is mastic asphalt and consists of a two-lane dual carriageway and cycle/footpaths on each side.

[5][6][7][8] The bridge has 15 spans in total and rests on 14 diamond shaped piers which have been designed to allow air to circulate freely around them.

In the event of the bridge traffic numbers increasing the cycle tracks can be configured to include a third lane.

[9][10][11] It is the only bridge in Scotland with single cables over central main supports and was in this respect a precursor of the Millau Viaduct in France.

[14] The ceremonial plaque of the opening can be seen on the railings of the western footpath, at the centre of the main span.

There is also a camera that takes photos of the vehicle from side-on which can identify the haulage company at fault.

Historical items found at the site include Roman coins known as sestertius and a crannog which is an artificial island.

Its main function is to divert traffic away from Glasgow and the urban stretches of the A82 which run through the city's West End and outer suburbs.

The tolling booths were situated at the south side of the bridge and were constructed by Culford Art Metal.

[19] At this point the contract for toll collection was put out to tender and was re-awarded to Apcoa from 1 April 2002.

[23][25] In the last accounting period between 1 April 2006 - 2 July 2006 whilst the tolls were free the bridge saw an increase in traffic on the previous year by 27.33%.

The first was a boy who was born 19 September 1990; he was subsequently named Oliver Erskine Edwards in homage to the bridge.

[29] An oil rig called the Texaco Captain collided with the road deck on 4 August 1996 resulting in the closure of the bridge.

A Royal Navy Westland Sea King helicopter from HMS Gannet, coastguard teams and officers from Strathclyde Fire and Rescue Service were all called out to the bridge following the incident.

[34][35][36][37][38][39][40] This has led to the Samaritans charity placing signs at each path leading onto the bridge and also within four public telephone boxes that are situated on the twin footpaths running adjacent to the roadway on either side of the river.

The bridge was brought into the media spotlight again after the death of two teenage girls who absconded from a nearby secure unit.

Highway Barrier Solutions are undertaking the upgrade which will cost £6 million and whilst ongoing the traffic is being monitored by Bluetooth technology.
