I was just thinking about how since the Gympie Bypass opened, SR15, SR49, and SR51 have all terminated at an unnumbered road (Old Bruce Hwy). Maybe SR15 could be decommissioned, SR49 could follow Old Bruce Hwy up to the Curra interchange, and SR51 could be extended via Old Bruce Hwy, Channon St, Horseshoe Bend, Stewart Tce, Bath Tce, Wolvi Rd, Gympie Connection Rd, then along the route of SR15.
