); north of this point, Cameron Sideroad continued northward (3.51 km within the post 1993 city limits) to Highway 7.

This bridge was named in memory of Londoner Guy Lombardo, who had recently died and had often played at nearby Wonderland Gardens.

At the same time, a four-lane diversion was built to the west of the original alignment between Commissioners Road and Springbank Drive.

In 1987, a new four-lane bridge was built over the Canadian Pacific Railway just south of Sarnia Road, replacing a two-lane level crossing.

Wonderland Road was separated by Highway 401 from the southernmost section to the Elgin County line, until 2015.

On October 31, 2014, London's first roundabout with four lanes opened at the intersection of Wonderland and Sunningdale.

It features a combination of on-street and off-street bike lanes from north of Fanshawe Park to Commissioners Roads, resuming at Southdale and ending at Bradley Avenue.

The road is served by multiple bus routes of the London Transit Commission.

Long term plans initially called for Wonderland Road to be widened to six lanes from the Highway 401 interchange to London's north city limits.
