These places listed below are more specific than general City traffic/congestion.
Boston, MA
Interstate 93 north and south
Boston's central artery has been the site of one of the most complex public works projects in history (called the "Big Dig") because it includes the entire elevated pass through downtown. The on-going project is already reaping benefits and small sections have been opened for bus travel. The project will replace a roadway built in the 1950s to carry 90,000 vehicles daily, but it now overflows with more than 200,000 vehicles each day. The project replaces the six-lane elevated highway with an eight-to-10-lane underground expressway directly crossing the Charles River.
Chicago, IL
Interstate 88 at the Eisenhower Expressway
Traffic from the west comes to a halt as 34,000 vehicles from I-88 merge with 43,000 vehicles from the Eisenhower Expressway (I-290). The road goes down to a single lane for several hundred yards before opening up to multiple lanes. What should be a 20-minute trip to the city may end up taking well over an hour, especially for buses as they work into the reduced lanes.
Dallas, TX
Interstate 35 at Interstate 30
Known as the "Mix Master" by local drivers, these two highways merge and struggle to carry more than 200,000 vehicles per day from downtown through the steep hills of "The Canyon."
Los Angeles, CA
Interstate I-710 Freeway
This freeway currently carries over 47,000 trucks per day. This is almost equivalent to 15 percent of the nation's total sea-borne cargo volume. The movement of goods to, from and through Southern California will continue to grow as the region's economy and population does. The existing configuration cannot handle current traffic volumes and the anticipated increases will make the heavily congested conditions even worse.
Los Angeles, CA
US 101/405 Interchange
Located in the San Fernando Valley area north of Beverly Hills, this intersection handles traffic headed for downtown Los Angeles from west and north of the city. Traffic congestion lasts for about five hours every weekday afternoon. Alternative routes are strongly suggested
Salt Lake City, UT
Interstate 15 and the SR-92 Interchange
Lakes to the west and the Wasatch Range to the east have funneled explosive traffic growth into this corridor. This interchange connects an existing two-lane highway to the interstate in a rapidly developing area. It is predicted that traffic increase 275 percent in the next five years alone.
Atlanta, GA
Interstate 75 at I-85 Interchange
Known as the "Downtown Connector" the highways combine about three miles north of downtown Atlanta, then pass through midtown and downtown Atlanta heading south. This interchange has one of the highest volumes of highway traffic in the country, carrying more than 340,000 vehicles per day. While the roadway leads to most of the hotels and attractions of the city, through traffic should find other routes. However lanes for multi-passenger vehicles do not continue along the entire route.
New York, NY
G.W. Bridge Exit Ramp for North Bound Major Deegan Expressway
This spiraling ramp is complicated because vehicles including many buses and trucks must weave across two lanes to get to the upper level of the George Washington Bridge. The result is traffic jams on both the Deegan and Cross Bronx expressways. Traffic jams can last from 7 a.m. to 10 a.m. and in the evenings from 3:30 p.m. to 7 p.m.

Guess they have a Highway named after me in Dallas and I didn't even know it!
