OKRoads -- Interstate 579 Pennsylvania

Interstate 579 connects the Liberty Tunnel to Interstate 279 in the eastern part of downtown Pittsburgh. Interstate 579 does not directly connect to Interstate 279 South or to either direction of Interstate 376. Exit numbers are not used on the 1.57-mile interstate.

Interstate 579 North
	Interstate 579 North begins on the Liberty Bridge over the Monongahela River. Obviously, the bridge is not up to interstate standards, as there is no division between opposing directions of traffic. The speed limit on the bridge is 40 mph. The first exit at the Boulevard of the Allies is 1/4 mile ahead. (Photo taken 7/8/05)
	Continue on Interstate 579 North to the Centre Avenue exit to Mellon Arena and the David Lawrence Convention Center. (Photo taken 7/8/05)

Scenes Related to Interstate 579
	The Boulevard of the Allies (unsigned Pennsylvania 885) is used to connect Interstate 376 to Interstate 579. Here we see westbound Boulevard of the Allies as it passes Mercy Hospital. Use Interstate 579 North to 7th Avenue to parking for PNC Park and Heinz Field. Both stadiums are located on the opposite side of the river. (Photo taken 7/8/05)
	With Duquesne University immediately to the right, travelers are advised to use Interstate 579 North to Mellon Arena and the Convention Center. (Photo taken 7/8/05)
	Boulevard of the Allies does continue west of Interstate 579, but there is no direct connection to its westbound continuation. So motorists are instead given a choice of which direction of Interstate 579 to travel on. Interstate 579 South is simply signed as "TO U.S. 19/Pennsylvania 51". (Photo taken 7/8/05)
