It's two years behind schedule, but the Manitoba government says a promised health-care bus will be on the road by the end of this year.

Health Minister Theresa Oswald says work is well underway to equip the bus and have it up and running in the Russell region.

The mobile primary care clinic was first promised in the NDP's 2010 throne speech.

The idea is to bring diagnostic services such as blood-sugar tests, as well as health advice, to outlying communities.

The project was pushed back to 2012 and, later, to this year as the province sought to overcome technical hurdles.

One of the chief concerns was ensuring the bus could be equipped with backup electrical power to protect equipment.

Oswald says another challenge was to install an X-ray machine while protecting workers from repeated exposure.

The bus will be staffed by a nurse and a nurse practitioner.

Oswald says eventually, two more buses will be added to serve southern Manitoba and the Interlake region.
