From a road condition point of view, the RHVP is top notch, when not flooded out
But seriously, it has flooded out at the Barton interchange what, three times since it opened in 2007? From what I understand it was investigated and they found an issue with debris collecting in front of the storm overflow drains that was causing the flooding, and this has since been corrected by modifying the grates and ensuring debris does not collect there anymore. The last major downpour a month ago did not cause any flooding on RHVP (the one where the Kenilworth underpass for the CN line flooded out).
