Robertson Road is a four-lane route along its entire length and the speed limit is 80 km/h (50 mph) except within Bells Corners where it is 60 km/h (37 mph). The route west of the old CP Rail trestle (now the Trans Canada Trail) passes through the Greenbelt and is designated as a high risk deer collision corridor. Numerous attempts have been made to reduce the risk, including reflective markers along the shoulder on each side of the road. Most recently, these have been removed and lighting installed.
Construction was completed in the fall of 2013 around the intersection with Moodie Drive. New storm sewers were installed and Robertson was widened from four lanes to six to ease peak period congestion. As well, the traffic lights at the Moodie Drive intersection were upgraded to have protected left turns for traffic turning from Moodie onto Robertson, as opposed to the unprotected left turns previously installed.
History
Robertson Road was named for John Robertson (1797-1884), an owner of a general store in Bells Corners and "Surveyor of Roads" for the Township of Nepean.[1]
Originally built as the concession road leading west to the Hazeldean neighbourhood in neighbouring Goulbourn Township, the road was named Arnprior Road because from there it headed northwest to the town of Arnprior. It was known colloquially as "Whiskey Road" for the number of taverns along its route.[2] It later became part of Highway 7 and Highway 15 before the western leg of Highway 417 was completed, after which it was known for a time as "Old Highway 7 & 15". The name Robertson Road was established on September 28, 1983, by a Regional Municipality of Ottawa-Carleton (RMOC) by-law naming the portion of Highway 7 and 15, west of the now Old Richmond Road turnoff at Bells Corners to Eagleson Road.[3]
