Reply #63: you're right-- Illinois has specific roads designated "expressways..."

...and the term is not applied generically there, e.g. Edens Expressway. Nationwide it's a more generic term:

An expressway is a divided highway, usually 4 lanes or wider. Beyond that basic requirement, the specific meaning of expressway depends upon the locality.

From the Illinois drivers manual:

Bicyclists
On most roadways, bicyclists have the same rights and responsibilities as other roadway users. Bicyclists are prohibited on limited-access highways, expressways and certain other marked roadways. Following are laws and safety tips you should know:

• Bicyclists are required to travel in the same direction as vehicles.
• Bicyclists should travel just to the right of faster moving traffic. However, certain hazards, such as rough surfaces, debris, drainage grates or a narrow traffic lane, may require bike riders to move toward the center of the lane.
• Drivers must yield the right-of-way to a bicyclist just as they would to another vehicle.
• When passing a bicyclist do so slowly and leave at least 3 ft. of passing space.
• A motorist should not park or drive in marked bike lanes.
• When following bicyclists, give them plenty of room and be prepared to stop quickly. Use extra caution during rainy and icy weather. At night do not use high beams when you see an oncoming bicycle rider.
• After parking and before opening vehicle doors, a motorist should first check for bicyclists.
• When a motorist is turning left and there is a bicyclist entering the intersection from the opposite direction, the driver should wait for the bicyclist to pass before making the turn. Also, if a motorist is sharing the left turn lane with a bicyclist, stay behind them until they have safely completed their turn.
• If a motorist is turning right and a bicyclist is approaching on the right, let the bicyclist go through the intersection first before making a right turn. Remember to always signal your turns.
