The tunnel was originally scheduled to open Wednesday, but the contractor was awarded $71,500 for each day it finished ahead of schedule.

The 52-year-old tunnel was closed for renovations on Dec. 27, creating traffic headaches for commuters and residents.

The renovation was planned after a corroded wall panel fell onto the roadway in December 2012. No one was hurt and no vehicles were struck.
