State Route 151 is a collection of routes in the Illawarra region, south of Sydney that are strung together to form a major through route from Wollonong to Dunmore. The route can be used as an alternate route to the Princes Highway (SR60) which takes an inland route. SR151 follows the coast most of the way instead. In fact part of the route (Shellharbour to Dunmore) once formed the main route from Wollongong to the South Coast. Some of the route forms part of Grand Pacific Drive.

This page looks at the segment of Shellharbour Road (now Dunmore Road), which was decommissioned in 2009 in the Dunmore area, and the section of Shellharbour Road between Dunmore, Shell Cove and Shellharbour which was upgraded to dual carriageway.

• 1920: The route was proclaimed the Princes Highway south of Shellharbour. 1
• 1931: Princes Highway moved to the now bypassed Dunmore alignment. 1
• 1974: State Route 151 was introduced.
• 2008: Work concludes on dual carriageway upgrade between Wattle Rd and Shell Cove.
• Mid 2009: Work ends on the section between Shell Cove and Dunmore Road.
• 29 November 2009: Opening of current SR151 alignment along current alignment between Old Shellharbour Rd and Lindsays Ln. 2

	Tabbita Road / Shellharbour Road Interchange: Dunmore. This is the exit ramp from the North Kiama Bypass and the former southern terminus of SR151, note the level crossing which runs over the ramp. The railway also runs parallel to Tabbita Road and under the Princes Highway. January 2006. Image © Paul Rands
	At Grade Crossing at Dunmore: As a result of the northern end of the North Kiama Bypass not being completed until it was connected with the Dunmore Deviation, northbound traffic for SR151 once had to cross the Princes Highway's temporary southbound carriageway to access the road.

	Northbound at Dunmore: Heading up the hill at Dunmore on what used to be known as Jamberoo Road, January 2006. Note the old Slow Vehicle Lane Ahead sign on wooden post. Image © Paul Rands
	ID Signage: Northbound at Shell Cove, January 2006. Note the unusual installation of separate flashing lights on the warning sign. Normally a pair of lights such as these is a standard traffic lantern with the centre lamp housing blacked out. This is an older style setup, although the signals in the distance were quite new when this was taken. Image © Paul Rands
