[8] In 1885–1886 the Department of Public Works removed the wall on the upstream (i.e. western) side of the bridge to widen it, and put up the present railing at the same time.

In 1934–1935 this new section was removed, the Department of Main Roads widening the bridge in order to handle increased traffic.

This modification saw the replacement of the cantilevered walk-way with an open concrete type and the straightening of the curved western face.

[14] However, there was a delay attributed to archeological investigations[15] that uncovered a sandstone pier and timber girders of the second bridge on that site, built between 1802 and 1804.

[4] While both portals opened in 2015,[16] the southern tunnel was closed off to assist with the construction of the Parramatta Light Rail (completed in 2024), and The Lennox, a riverfront high-rise residential apartment building, which will include a new public walkway on the western side of the southern tunnel.

[5] Lennox Bridge, Parramatta was listed on the New South Wales State Heritage Register on 2 April 1999.
