The future of Preston Bus Station is to be guaranteed with a multi million pound cash injection.
Preston City Council and Lancashire County Council are set to agree an £8.3m investment in the Grade II listed building.
A new multi-million pound transport interchange has opened in Rochdale.
It will offer new facilities for bus passengers and will link directly with the new Metrolink extension.
It is the first building of its kind in Europe to be powered by hydro-electricity.
Cllr Colin Lambert Leader, Rochdale Council
I am pleased the Department for Transport has been able to support this scheme. It will make bus travel more attractive in Rochdale, promoting growth and cutting carbon. Redevelopment of the existing bus station site is expected to bring some 1,500 new jobs into the town.
Rochdale’s £11.5m transport interchange opens its doors to the public later. Transport for Greater Manchester say it will provide enhanced levels of facilities and improved safety and security for bus passengers and will link directly with the new Metrolink extension.
I am delighted that we have completed this innovative and hugely significant project that will provide a fantastic, modern gateway for the town centre and a European first, thanks to its hydropower plant.
The interchange will provide better links between rail and bus services as well as improved waiting areas, passenger facilities, accessibility, information, safety and security.
The facility is also going to play a crucial part in making Rochdale an exciting destination for residents, shoppers and businesses alike.”
Motorists in Manchester and Liverpool have to put up with some of the worst traffic jams in the country.
A new study puts both cities in the top ten of most congested places.
It claims drivers in Manchester suffer more than 30 minutes of rush hour delays each day.
In Liverpool, motorists sit in traffic jams for an average of 23 minutes.
Manchester was seventh in the league table and Liverpool was placed tenth.
The worst place for traffic congestion was Bristol. London was placed fifth in the rankings.
The research was conducted by sat nav company Tom Tom which said it has studied "trillions" of journeys across the world since 2007.
A new scheme to support electric cars in Greater Manchester is being revealed.
A network of car charging points across the county will be available from summer. The leader of the city council will launch the £2.7m project later.
Transport Secretary Patrick McLoughlin has said that those who need to sell their house but struggle because of the HS2 plans will still be helped and that he wants the line, "to create jobs and prosperity not to harm it."
"I understand how proposals like this can affect the property markets so compensation will be as generous as on the first phase, and more generous then when we built the motorways."
Transport Secretary says that the HS2 will be first main line north of London for nearly 120 years.
Patrick McLoughlin has told the House of Commons that it is not just about faster trains to London - but about how our greatest cities are linked.
Mr McLoughlin said he is determined that HS2 benefits will be spread much wider than just those places served by the line.
