The cost of a planned bridge between Govan and Partick in Glasgow has soared by £12m, a council report has revealed.

Glasgow MSP Paul Sweeney has said he is “astounded” that the cost to deliver “this fairly basic pedestrian swing bridge” has risen to £30m.

However, a council spokesman said the bridge will bring “significant economic, environmental and social benefits” and requires “very complex” engineering.

Councillors are being asked to back awarding a £29.5m contract to construction firm Farrans next week — but the original estimated project budget was £17.5m.
