Burnside's road system was completely bitumenised during the 1960s and 1970s through government-sponsored roadworks programmes. Plans were also laid out to replace the winding and dangerous Mount Barker Road. One of these proposals was the Burnside-Crafers Highway, which was strongly supported by council; it envisaged leaving Greenhill Road once reaching Hazelwood Park. It was then to pass through Hazelwood Park and Beaumont, wind around the hills of Waterfall Gully and then go over Eagle on the Hill to meet Crafers. The Burnside Council put much effort into this proposal, widening Linden Avenue (which runs north-west to south-east) in preparation for the highway. The proposal was eventually rejected in favour of upgrading Mount Barker Road and Linden Avenue remained a huge out-of-place road running through an otherwise peaceful suburb.
