The City of Ottawa recently began construction at the intersection of Baseline and Greenbank roads for the Baseline/Greenbank transit priority intersection improvements project.

—

Overhead utility work and underground duct work is ongoing, with storm sewer catch basin removals and installation underway over the coming weeks.

This reconstruction will bring improvements to the intersection including dedicated bus priority lanes, new concrete sidewalks and curbs, raised asphalt cycle tracks, and reconfigured traffic lanes. It will also include enhanced pavement markings and signage on Baseline Road, from Offenbach Lane to Constellation Drive.

Traffic impacts

Baseline Road, from Cornell Street to McWatters Road, and Greenbank Road, between Lisa Avenue and Monterey Drive, will have lane reductions in both directions. These impacts are expected to last until late November 2025.

Traffic delays throughout the construction zone are expected due to the ongoing lane reductions. Signage will be in place to notify residents of the impacted area, and temporary traffic calming measures have been installed on some adjacent local streets.
