A Pittsburgh landmark! This tunnel is old and been here for quite the time. I feel like everyone in Pittsburgh has a love hate relationship for it. I think the mornings and night are a hit or miss on traffic being sometimes there's construction slowing things down. And rush hour traffic here is a nightmare between 4 to 6. One thing I can say is people coming from the airport into town or just coming out the other side it's just a huge shot of the city. To the left you have the stadium, casino, science center. To the right you have giant buildings a shot of the river and it just a all around good view. All traffic issues aside this tunnels great. It's a must see for anyone new to the area.
