The US government has deployed a team of contractors to oversee construction of a massive network of bridges, tunnels and roads to link the cities of Houston, Dallas and St. Louis.
The project, which will cost $1.6 trillion, will involve constructing a network of thousands of miles of underground pipelines, viaducts and bridges, with a total of 10,000 miles of construction planned across the US.
The government estimates the total cost of the project will be $1,200 per mile of highway, including construction costs, maintenance and the cost of rehabilitation and maintenance.
The plan calls for the network to be completed by 2024, a timeline that seems a lot longer than many analysts are predicting.
While the government has put a price tag on the construction, a government study published in March suggested the total construction cost for the project is $2.2 trillion, according to The Wall Street Journal.
It will also require a $2 trillion infrastructure investment that includes roads, bridges, sewer systems, power lines, electrical substations, water treatment plants, airports, schools and more.
The work is being done by a group of US firms, including Halliburton, KBR and Parsons Brinckerhoff.
The Department of Transportation and Department of Energy are coordinating the project with the US Department of Housing and Urban Development.
