Major repair work begins Monday on the Alexandra bridge linking Ottawa and Gatineau.
Until the end of June, the Gatineau-bound lane will be closed.
The Ottawa-bound lane will be closed from Mondays to Wednesdays between 9:30 a.m. and 3 p.m.
Its direction of travel will also be changed to allow Gatineau traffic to head home -- between 3 p.m. and 7 p.m. Mondays through Wednesdays, and 2 p.m. to 7 p.m. on Thursdays and Fridays.
The federal public works department is also warning that the entire bridge will be closed to vehicles on occasional weeknights and weekends.
The boardwalk will remain open for pedestrians and cyclists, but officials warn they should use extra caution.
