This is 10th Avenue in Vancouver; people on bikes use this traffic-calmed bikeway in droves, especially this stretch of East 10th Ave passing through China Creek South Park at Clark Drive.
Presumably, at one time, 10th Avenue here was open to motor vehicles, bisecting the park.
It also looks like the Union Bikeway, one of Vancouver’s busiest, which runs through Strathcona Linear Park at Union St. near Hawks Ave. and is part of traffic-calming on Union St.
And also in Lilian To Park at Yukon and 17th.
