Lakeview Avenue Bridge Pile Driving Anticipated to Begin Thursday, Aug. 28
Progress continues at the SR-91/Lakeview Avenue Interchange as crews prepare for construction of the new Lakeview bridge. Pile driving is anticipated to begin on Thursday, Aug. 28.
Pile driving is anticipated to begin Thursday, August 28 and continue in phases through early October, on weekdays. Crews may be on the worksite as early as 6 a.m. and are anticipated to perform pile driving activities at 7 a.m. to 4 p.m.
While pile driving is a critical step in the construction process, it may also be noisy and cause some vibration. The construction team will monitor noise and vibration levels throughout the activity.
What is Pile Driving?
Pile driving is a common construction method used to build a strong foundation of large structures, such as bridges. During this process, long steel beams, known as piles, are driven deep into the ground with the help of a powerful hammer mounted on a construction rig.
As of July 7, 2025, Eastbound SR-91 Loop On-Ramp is Closed for Approximately Two Years
