More than half a million pounds will be pumped into stabilisation works for the town centre shopping thoroughfare, which connects Corporation Street with Market Place.
It is just one area of the town destined for revival courtesy of approved funding being released through Government grants.
Kirklees Council has secured £2.7m from the Getting Building Fund and the Towns Fund.
Improvements are earmarked at Dewsbury Station and in the area of the library along with a pedestrian subway, public art, new lighting in the Kingsway and Queensway arcades, and investment at 15 Union Street to make a “creative hub”. In total £750,00 will be spent.
Dewsbury Arcade and Huddersfield’s George Hotel will share in a further £1.9m, with work getting underway next year.
Coun Peter McBride, the council’s regeneration champion, said the £600,000 being allocated towards Dewsbury Arcade represented a major contribution towards refurbishment costs.
He added: “These are very welcome and very helpful in developing parts of Dewsbury and Huddersfield.”
Coun Cathy Scott (Lab, Dewsbury East) said the cash boost was “great news”.
She added that the arcade “is going to be a great asset as we move forward, particularly in these times that we’re facing. It shows continuity of things that are happening.”
