Tuesday's NSW state budget includes an additional $50.77 million for the project, which broke ground last year.

In last year's budget the state spent $65 million on the project.

Armidale Secondary College, billed as a "revolutionary" new school was given a date for completion, with Member for Northern Tablelands Adam Marshall saying it would open in time for the class of term 1, 2021.

The super school will support 1500 students, and swallow the entirety of Armidale and Duval High Schools' student cohorts.

"The Armidale Secondary College will change the face of education in the Northern Tablelands for generations to come," Mr Marshall said.

"It's incredibly exciting to think it won't be long and we will begin to witness the foundations of the new facility coming together with modern laboratories and enhanced design and technology spaces, advanced vocational education facilities and new sporting fields and courts."

"With its greatly-expanded curriculum delivering the full range of Stage 6 (Years 11 and 12) subjects and potential to offer all Vocational Educational Training Framework, I feel Armidale will be among the best prepared regional cities to meet changing workforce needs and changing local economies."

With Armidale high school in the process of demolition, students from both schools will continue to be squeezed into Duval for another year and a half.

The school will also feature a multipurpose performing arts centre on campus, at a cost of $18 million. The facility will feature a recording studio, seating for 425 and will be made available for travelling productions and conferences.

The Express exclusively revealed the plans before an announcement in 2017.

The state budget has spent a record amount of money on infrastructure in New England. From hospitals to 24 hour police stations, the New England has received $304.3 million of bricks and mortar in today's state budget, most of which has gone to meeting election promises.

The state will also begin planning for new Glen Innes and Moree hospitals, spend an additional $19.8 million for the two-stage Inverell hospital and construct a new 24 hour police station in Inverell.

Both Glen Innes and Moree hospitals are still slated to be started before the next state election in March 2021 but have no planned date of completion.

In terms of transport infrastructure, the government plans to spend $85.9 million on roads, plus $1.7 million on an upgrade of Armidale railway station, though most of that spend will go to an upgrade of the Newell Highway.

There will also be a new truck wash in Moree and another in Warialda and $120,000 for new local footpaths in Uralla, Armidale and Inverell.

The budget will also subsidise council road maintenance to the tune of $10.93, locked in $6.45 million upgrading the Guyra water pipeline from Malpas Dam and spend $4.26 million on social housing in Moree and Boggabilla.

The government has budgeted to spend $3.5 million in 2019-20 to start a new John Hunter "Health and Innovation Precinct" in Newcastle, which will ultimately cost $780 million.

The state will spend just over $2 million planning the Tenterfield bypass, part of an overall spend to date of $7.5 million.

NSW will also spend $1.8 billion fighting the drought and has cut payroll tax for small business of turnover up to $1 million over the next three years in an effort to encourage employment growth.
