Much new quality housing has been constructed on the northern fringes of the town, in order to service the demand for commuter housing. With a journey time of 20 minutes from Kilmarnock to Glasgow (roughly half that of the existing train service), the M77 motorway has transformed the link between Glasgow and Kilmarnock. The upgrading of the A77 route to Glasgow to the M77 motorway in 2005 has made Kilmarnock more accessible for commuters, and recent house price increases have reflected this.
