I-35W Saint Anthony Falls Bridge
The I-35W Saint Anthony Falls Bridge crosses the Mississippi River one-half mile (875 m) downstream from the Saint Anthony Falls in Minneapolis, Minnesota in the U.S., carrying north–south traffic on Interstate Highway 35W. The ten-lane bridge replaced the I-35W Mississippi River bridge, which collapsed on August 1, 2007. It was planned and is maintained by the Minnesota Department of Transportation (Mn/DOT).

Eastern Span Replacement Of The San Francisco–Oakland Bay Bridge
The eastern span replacement of the San Francisco–Oakland Bay Bridge was a construction project to replace a seismically unsound portion of the Bay Bridge with a new self-anchored suspension bridge (SAS) and a pair of viaducts.

Circle Drive
Circle Drive is a major road constructed as a ring road in Saskatoon, Saskatchewan, Canada. Its route constitutes both part of the Yellowhead Highway and Highway 11, signed as both along the entire length. It was first conceived in 1913 by the city commissioner and completed exactly 100 years later in 2013. Most of the route is a fully-controlled access freeway, however the segment between Airport Drive and Millar Avenue has at-grade intersections. History Construction of a ring road in Saskatoon was first proposed in 1913 by city commissioner Christopher J. Yorath. He conceived the first comprehensive town plan, which included inner and outer "encircling boulevards". Parts of the present-day roadway follow the course Yorath laid out, though some route proposals were rejected, such as one for the southern leg that would have taken the roadway over an island south of present-day Saskatoon that, years later, was named in honour of Yorath. It wasn't until the 1950s as the city exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Mann Bridge
The Port Mann Bridge is a 10-lane cable-stayed bridge in British Columbia, Canada that opened to traffic in 2012. Carrying 10 lanes of traffic with space reserved for a light rail line, it is the second widest bridge, after the San Francisco-Oakland Bay Bridge. The cable-stayed bridge replaced a steel arch bridge that spanned the Fraser River, connecting Coquitlam to Surrey in British Columbia in the Vancouver metro area.

The old bridge consisted of three spans with an orthotropic deck carrying five lanes (originally four lanes) of Trans-Canada Highway traffic, with approach spans of three steel plate girders and concrete deck.
