Relief, finally, has arrived for Riverside Dr. commuters.

The major east-west road connecting downtown and London’s west end finally reopened to commuters Thursday morning after a lengthy delay in the completion of months of construction.

“Riverside Dr. is open to traffic,” Edward Soldo, city hall’s transportation boss, tweeted early Thursday. “Thank you for your patience during construction.”

Repairs started in early June were scheduled to be done by Aug. 21. But completion was delayed until now, prompting frustration from drivers and creating traffic bottlenecks.
