Question: Was Duluth Ship Canal or Cross Florida Barge Canal cancelled for environmental reasons?

full_context: Document 1: Miami River Greenway: The Miami River Greenway is an urban greenway project in Miami, Florida located along both banks of the Miami River. The plan is for it to eventually form an uninterrupted walkway from the mouth of the river in Downtown Miami to the Dolphin Expressway near the Civic Center area, and in the long term all the way to Miami International Airport. On the north bank the walkway is currently known as the Miami Riverwalk which currently extends beyond the river through Bayfront Park along Biscayne Bay where it is known as the Bay Walk. Plans are to extend this as far north and south as the Julia Tuttle and Rickenbacker Causeways, respectively.
Document 2: Duluth Ship Canal: The Duluth Ship Canal is an artificial channel cut through Minnesota Point, providing direct access to Duluth harbor from Lake Superior. Begun privately in 1871, it was put under federal supervision and maintenance several years later. It is still an important component of the harbor facilities.
Document 3: Duluth South Breakwater Inner Light: The Duluth South Breakwater Inner Light is a lighthouse on the south breakwater of the Duluth Ship Canal in Duluth, Minnesota, United States. It forms a range with the Duluth South Breakwater Outer Light to guide ships into the canal from Lake Superior.
Document 4: Cross Florida Barge Canal: The Cross Florida Barge Canal, now officially the Marjorie Harris Carr Cross Florida Greenway is a protected green belt corridor, one mile (1.6 km) wide in most places. It is named for the leader of opposition to the Cross Florida Barge Canal, a canal project to connect the Gulf of Mexico and the Atlantic Ocean across Florida for barge traffic. Two sections were built but the project was cancelled, mainly for environmental reasons.
Document 5: Canaveral Barge Canal: The Canaveral Barge Canal provides an east-to-west link between the Atlantic Ocean and Indian River Lagoon across northern Merritt Island, Florida, in two segments separated by the Banana River. It is located 15 miles south of Titusville, Florida. The canal is 12 feet deep and has entrances to other water systems including Syke's Creek and various marinas. The canal links Port Canaveral along the Atlantic Ocean to the Intracoastal Waterway running down the center of the Indian River Lagoon. The canal was constructed to allow the transport of crude oil by barge to the two power plants south of Titusville, Florida.
Document 6: North Shore Channel: The North Shore Channel is a drainage canal built between 1907 and 1910 to flush the sewage-filled North Branch of the Chicago River down the Chicago Sanitary and Ship Canal. The sewage carrying duty has been largely taken over by the Chicago Deep Tunnel, but there are still occasional discharges due to heavy rains.
Document 7: Duluth South Breakwater Outer Light: The Duluth South Breakwater Outer Light is a lighthouse at the end of the south breakwater of the Duluth Ship Canal. It forms a range with the Duluth South Breakwater Inner Light.
Document 8: Superior Bay: Superior Bay is a narrow inlet of Lake Superior along the border of Minnesota and Wisconsin. It is 7 miles long and 0.5 miles wide. A small strait connects it to the Saint Louis Bay to the west, into which the Saint Louis River empties. Superior Bay is located between the city of Superior and the Park Point neighborhood of Duluth. The Duluth Harbor Basin is nearby.
Document 9: Coast-to-Coast Connector trail: The Coast-to-Coast Connector bicycle trail is a proposed 250 mile bicycle and multi-use trail across Florida. The trail would provide a path connecting the Gulf of Mexico on peninsular Florida's west coast to the Atlantic Ocean on Florida's east coast. Legislation in support of the planned trail passed the Florida House of Representatives in April 2014 and would fund it with $15.5 million. Florida State Senator Andy Gardiner of Orlando is one of the plan's leading supporters. Legislation funding the trail with $50 million was vetoed in 2013 by Governor Rick Scott in 2013. The funding would be used close gaps in the trail route. The estimated cost of the project is $45 million. It would incorporate existing public spaces and trails including:
Document 10: Florida Ecological Greenways Network: Florida Ecological Greenways Network work to provide a "system of native landscapes and ecosystems that supports native plant and animal species, sustains clean air, water, fisheries, and other natural resources, and maintains the scenic natural beauty that draws people to visit and settle in Florida,” as stated Florida Greenways Commission. It also functions to devise a plan for a statewide greenways system, based on GIS (Geographic Information System) technology and suggestions from the public. The GIS data used includes soil, water, and geological information, wildlife movements and habitat data, as well as existing trails and parks, transportation and infrastructure fixtures, educational and historical sites, and political boundaries. This system would be created in accordance with the December 1994 report from the Florida Greenways Commission to the Governor of the state of Florida, a report which outlined the protocol for creating it. Such a system would connect all aspects of the state’s “green infrastructure”, making it more comprehensive for use by the state’s citizens and more effective in achieving greater sustainability throughout the state of Florida for generations to come.
Document 11: Duluth North Pier Light: The Duluth North Pier Light is a lighthouse on the north breakwater at the entrance to the Duluth Ship Canal.
Document 12: Boca Grande Bike Path: The Boca Grande Bike Path is a 6.5 mile multi-use path in Boca Grande, Florida on Gasparilla Island. The northern portion of the path runs on the former right of way of the Charlotte Harbor and Northern Railway, which operated on Gasparilla Island from 1907 to 1981. As Florida's first rail trail, it was principally built for bicycles, but pedestrians also use it. Golf carts are also permitted on the path. Another trail exists on the mainland portion of the railroad line known as the Cape Haze Pioneer Trail.
Document 13: Schuylkill Canal: Schuylkill Canal is the common, but technically inaccurate, name for the Schuylkill Navigation, a 19th-century commercial waterway in and along the Schuylkill River in the U.S. state of Pennsylvania. The "canal" was actually a system of interconnected canals and slack-water pools in the river, which is called a navigation. Chartered in 1815, the Schuylkill Navigation opened in 1825 to provide transportation and water power. At the time, the river was the least expensive and most efficient method of transporting bulk cargo, and the eastern seaboard cities of the U.S. were experiencing an energy crisis due to over forestation. It fostered the mining of anthracite coal as the major source of industry between Pottsville and eastern markets. Along the tow-paths, mules pulled barges of coal from Port Carbon through the water gaps to Pottsville; locally to the port and markets of Philadelphia; and some then by ship or through additional New Jersey waterways, to New York City markets.
Document 14: Brunswick–Altamaha canal: The Brunswick–Altamaha Canal was a 12-mile-long canal built to connect the Altamaha River to the city of Brunswick, Georgia at the Turtle River to transport goods from Brunswick's port to areas farther north and inland. It included locks on both ends of the canal. The canal was originally proposed in 1798 and after two failed charters (1826 and 1830), construction was started in 1836 by Thomas Butler King. The project was estimated to cost $450,000. The canal was finished and opened in 1854; however, by that time the canal was obsolete because of new railroads. The canal was closed by 1860. The Columbian mammoth was discovered during the construction of the canal.
Document 15: Duluth, Minnesota: Duluth is a major port city in the U.S. state of Minnesota and the county seat of Saint Louis County. Duluth has a population of 86,110 and is the second-largest city on Lake Superior's shores, after Thunder Bay, Ontario, in Canada; it has the largest metropolitan area on the lake. The Duluth MSA had a population of 279,771 in 2010, the second-largest in Minnesota.
