Glasgow Getting £20m Road Repairs
Glasgow council chiefs are ploughing £20million into filling potholes and sorting out the streets.
They've doubled investment in the city's roads and walkways.
Council leader Frank McAveety's revealed plans to pump an extra £8million into repairs - targeting at least 20,000 potholes.
The budget boost will also help resurface more than 200 residential streets and 50km of pavements - while carrying out enough permanent patch repairs to cover 23 football pitches.
Cllr McAveety said: "Glaswegians have every right to expect good roads and pavements - and I want to make sure we're doing everything we can to deliver the big investment required to match their expectations.
"We have already secured real improvements in the city centre and on some of our busiest routes across the city - but this additional cash will allow us to reach further into our communities and repair more residential streets than ever before.
"Our investment in Glasgow's roads is unprecedented in Scotland.
"That is good news for all road users - from drivers, cyclists and pedestrians to businesses that rely on Glasgow's infrastructure, create jobs and drive our economy."
Another girl was airlifted to hospital.
The attack happened on Waverley Bridge.
Opposition parties are criticising the figures.
