'Invest in the West' was launched to put pressure on Executive Ministers ahead of Stormont's annual budget.
It started after the UK Governments announcement that Northern Ireland will receive the multi-million pound windfall.
The group say the full amount should be allocated to projects in the west after 'years of neglect'.
Over 500 people have signed the petition.
They said "There are a number of long standing infrastructure plans for the west of Northern Ireland which currently have insufficient funding allocated and no completion deadlines (e.g. dualling the A5 and A6 roads, A4 Enniskillen Southern Bypass, improvements to the railway line between Derry/Londonderry & Coleraine).
"It is unacceptable that the western half of Northern Ireland has been left starved of the infrastructure it needs and deserves. We demand that ALL of this £277m infrastructure windfall be allocated by the NI Assembly to projects in the west of the province, to begin reversing the decades of historical neglect."
