History
Megarritys Creek Bridge is a concrete arch bridge spanning Megarritys Creek. The construction of the bridge provided a vital link across the Creek for the operation of the Warragamba Emergency Scheme. While it was designed eventually to carry the No 1 {{convert|106|in|cm|adj=on|order=flip}} outlet main from Warragamba Dam, for the Emergency Scheme it carried the {{convert|48|in|cm|adj=on|order=flip}} main from the weir to Prospect Reservoir.

Heritage listing
As at 22 March 2001, Megarritys Bridge is considered to be of high significance as it serves the function of carrying the major Warragamba pipeline across Megarritys Creek. It is historically associated with the Warragamba Emergency Scheme, and at the time of construction, was one of the largest concrete arch bridges to be built in NSW. It is a unique item of engineering heritage as its design is based on an innovative "bow string" arch design rather than the more common "decked" arch design.
Megarritys Bridge was listed on the New South Wales State Heritage Register on 18 November 1999 having satisfied the following criteria.
The place possesses uncommon, rare or endangered aspects of the cultural or natural history of New South Wales.
