Ottawa's Alexandra Bridge is set to be replaced within 10 years. It opened in 1901 as a railway bridge. It carried the Hull Electric Railway for a few decades. Although its usage as a passenger can bridge is fairly low (about 9% of interprovincial traffic), it carries 33% of pedestrians and cyclists.
Gatineau's LRT plans include this crossing. The Federal Government has also re-opened the 6th interprovincial bridge (or 7th if we count the abandoned PoW at the foot of the Trillium Line) debate that has been killed and resurrected countless times over the last 50 years. Both the cities of Gatineau and Ottawa are uninterested in the idea. Ottawa is currently studying a possible tunnel linking the Macdonald-Cartier Bridge (hwy 5) and the Queensway (hwy 417).
