The Welland Canal is a ship canal in Ontario, Canada, and part of the St. Lawrence Seaway and Great Lakes Waterway. The canal traverses the Niagara Peninsula between Port Weller on Lake Ontario, and Port Colborne on Lake Erie, and was erected because the Niagara River—the only natural waterway connecting the lakes—was unnavigable due to Niagara Falls. The Welland Canal enables ships to ascend and descend the Niagara Escarpment, and has followed four different routes since it opened.
The Queen Elizabeth Way (QEW) is a 400-series highway in the Canadian province of Ontario linking Toronto with the Niagara Peninsula and Buffalo, New York. The highway begins at the Canada–United States border on the Peace Bridge in Fort Erie and travels 139.1 kilometres (86.4 mi) around the western end of Lake Ontario, ending at Highway 427 as the physical highway continues as the Gardiner Expressway into downtown Toronto. The QEW is one of Ontario's busiest highways, with an average of close to 250,000 vehicles per day on some sections.
The 400-series highways are a network of controlled-access highways in the Canadian province of Ontario, forming a special subset of the provincial highway system. They are analogous to the Interstate Highway System in the United States or the Autoroute system of neighbouring Quebec, and are regulated by the Ministry of Transportation of Ontario (MTO). The 400-series designations were introduced in 1952, although Ontario had been constructing divided highways for two decades prior. Initially, only Highways 400, 401 and 402 were numbered; other designations followed in the subsequent decades. To this day, not all controlled-access highways in Ontario are a part of the 400-series highway network. The network is situated almost entirely in Southern Ontario, although Highway 400 extends into the more remote northern portion of the province.
King's Highway 58, commonly referred to as Highway 58, is a provincially maintained highway in the Canadian province of Ontario. The route is divided into two segments with a combined length of 15.5 km (9.6 mi). The southern segment travels from Niagara Regional Road 3, formerly Highway 3, in Port Colborne, to the Highway 58A junction in the southern end of Welland, a distance of 7.2 km (4.5 mi). The northern segment begins at Highway 20 near Allanburg and travels north and west to a large junction with Highway 406 at the St. Catharines – Thorold boundary, a distance of 8.3 km (5.2 mi). An 18.1 km (11.2 mi) gap separates the two segments within Welland and Pelham. The entire route is located within the Regional Municipality of Niagara.
King's Highway 417, commonly referred to as Highway 417 and as the Queensway through Ottawa, is a 400-series highway in the Canadian province of Ontario. It connects Ottawa with Montreal via A-40, and is the backbone of the highway system in the National Capital Region. Within Ottawa, it forms part of the Queensway west from Highway 7 to Ottawa Road 174. Highway 417 extends from the Quebec border, near Hawkesbury, to Arnprior, where it continues westward as Highway 17. Aside from the urban section through Ottawa, Highway 417 passes through farmland that dominates much of the fertile Ottawa Valley.
The Hampton Roads Bridge–Tunnel (HRBT) is a 3.5-mile-long (5.6 km) Hampton Roads crossing for Interstate 64 (I-64) and US Route 60 (US 60). It is a four-lane facility comprising bridges, trestles, artificial islands, and tunnels under the main shipping channels for Hampton Roads harbor in the southeastern portion of Virginia in the United States.

King's Highway 140, commonly referred to as Highway 140, is a provincially maintained highway in the Canadian province of Ontario. The highway connects Port Colborne near Lake Erie with Highway 406 in Welland, via the Main Street Tunnel. It was constructed in the early 1970s as part of the Welland Bypass project of the Welland Canal, which resulted in the severance of several highways and rail lines. Opened to traffic in late 1972, several months following the tunnel, Highway 140 has remained unchanged since, despite growing calls to resign it as an extension of Highway 406.
The Main Street Tunnel, located in Welland, Ontario, Canada, is an underwater tunnel, carrying Niagara Road 27 and the unsigned designation of Highway 7146 under the Welland Canal. It is named as a part of East Main Street.

Port Robinson is a small community in the southernmost part of Thorold, Ontario, Canada. The community is divided in half by the Welland Canal, as there is no bridge in the immediate vicinity to connect the two halves of the community. In the summer, a small free ferry for pedestrians and cyclists runs across the canal. In the winter, residents must use the bridge on Highway 20, which results in a 13.3 km (8.3 mi) trip to get to the other side.
King's Highway 20, commonly referred to as Highway 20, is a provincially maintained highway in the Canadian province of Ontario.

Allanburg is the capital of the City of Thorold, Ontario, Canada. It is located on the Welland Canal and Highway 20, both important transportation routes through the Niagara Peninsula. The two cross at a vertical-lift bridge, numbered as Bridge 11 by the Saint Lawrence Seaway Authority, but often known simply as the Allanburg Bridge. The collision of the ship Windoc with the bridge made national news in 2001.
King's Highway 58A, commonly referred to as Highway 58A, is a provincially maintained highway in the Canadian province of Ontario.

The Elizabeth River Tunnels Project, a series of transportation projects in the South Hampton Roads region of Virginia, comprises the rehabilitation of the Downtown and existing Midtown Tunnels, the construction of a new parallel Midtown Tunnel, and the extension of the MLK Freeway/U.S. 58 to I-264. Intended to reduce congestion on area surface streets and arterial roads, the project was administered by Elizabeth River Crossings (ERC) and Virginia Department of Transportation (VDOT) as part of a 58-year public-private partnership. ERC maintains and operates the project ongoing.
The Evergreen Point Floating Bridge, also known as the 520 Bridge and officially the Governor Albert D. Rosellini Bridge, carries Washington State Route 520 across Lake Washington from Seattle to its eastern suburbs. The 7,710-foot-long (2,350 m) floating span is the longest floating bridge in the world, as well as the world's widest measuring 116 feet (35 m) at its midpoint. It is a toll bridge and uses electronic collection.
