Plans for a £423m ’robust, sustainable and affordable’ capital programme were unveiled in the Budget.

The five-year programme includes a long-awaited replacement Castle Rushen High School and a £3m refurbishment of the swimming pools at the NSC.

Treasury Minister Alfred Cannan said the continued investment in infrastructure remains a strategic priority for government.

But he said the capital budget was underspent this year at £50m, that’s just 56% of the sum earmarked.

Mr Cannan said this was mainly due slippage in the timetable for the Douglas prom revamp and the replacement Eastcliffe the adult disability learning centre - both of which are now on track to start in the coming year.

Among other measures unveiled was £1m over the next four years to improve the pathways, play areas and car parks in the national glens.

Some £3.8m will be given towards active travel over the next four years, promoting walking and cycling as an alternative to using the car.

There is £14.5m for day-care and old folks facilities in Douglas and £11.5m over the next five years of work to transform Treasury IT systems.

Capital expenditure will be about £60m to £65m a year and there is a projected balance of £36m being in the consolidated loans fund in 2022-23.

Mr Cannan said this level of balance allows for some additional expenditure, providing flexibility.
