In the 1990s, the expansion of the bridge at Island Park was a major issue. The National Capital Commission proposed a fully grade-separated interchange to the River Parkway, with a major expansion in capacity of the bridge over the river. Organized opposition in Ottawa to the plans led to a reduced plan by the NCC. The bridge is three lanes, with the direction of the middle lane switched during different hours of the day. The NCC also built a signalized intersection at Tunney's Pasture at the time.
