Thanks to a fire ignited by construction on the Liberty Bridge mayhem ensued with motor traffic trying to get to and  from the South Hills. The bridge was forced to be shut down due to the fire damage.

We witnessed the fire first hand while riding from work to a doctor's appointment:




We later learned that the bridge was 'minutes from collapse'. Wow.

Hearing that Vannevar wanted to ride through the Liberty tunnels while they were closed to motor vehicles, we jumped at the chance. How often does an opportunity like this pop up?

And so, we did.
