C-470, a toll road on the west end of Denver, is often congested, and transportation officials propose expanding it to 10 lanes with a mixture of general-purpose lanes and tolled managed lanes. With a price tag of up to $2 billion, the plan also includes expanding Highway 93 and US 6 and adding a lane designed for autonomous vehicles.
The cost of building infrastructure in the US is astounding, but several startups in California are trying to use technology to make it less expensive. One uses a handheld device to create 3D contour maps, another employs software and machine learning to predict and respond to disasters, and another has developed a robot that can detect leaks in sewer pipes.
Landslides annually kill more people in the US than earthquakes but generate little attention, leading many to build in areas that are under threat. The solution lies in better mapping of the hazard to raise awareness of the risk and zoning that takes landslide potential into account.
A panel has released a plan to impose congestion pricing in Manhattan south of 60th Street using electronic tolling. Trucks would be charged $25.34 to drive to the busiest parts of the city, cars $11.52 and for-hire services such as Uber between $2 and $5 per ride.
The Orange County Transportation Authority in California will soon start construction on a $1.9 billion project to add toll lanes to Interstate 405. The 16-mile expansion is expected to take five years, and when completed, the interstate will be "the freeway of the future."
The Maryland Transportation Authority will soon take design-build bids for a replacement project for the aging Harry W. Nice Memorial Bridge, a toll bridge that crosses the Potomac River between Maryland and Virginia. The state has appropriated $765 million to the project, and the new bridge will have all-electronic tolling.
Seattle is to begin a pilot project on a per-mile-driven fee, and the rate will be 2.4 cents per mile, although no actual charges will be incurred. The rate is roughly equivalent to the fuel taxes paid by a motorist driving a vehicle that averages 20.5 miles per gallon, and the project will last one year.
A bill proposed by a Virginia state legislator would charge tolls to semitrucks on Interstate 81. The bill's sponsor, Republican Mark Obenshain, said tolls would provide much-needed revenue for the interstate.

Concrete continues to be placed into coffer dams at the bottom of the Mississippi River that will form foundations of the arches on the new $1 billion Interstate 74 bridge in Illinois and Iowa. Construction of the bridge, which began last July and will connect Bettendorf, Iowa, to Moline, Ill., is expected take about three more years.
