Bridge Demolition on Hwy 99 in Sacramento

Demolition at 21st Ave Undercrossing
Penhall was contracted by Bridgeway Civil for the demolition of the 21st Ave bridge undercrossing on Hwy 99 in Sacramento, a high-profile infrastructure project. The process began with slotting the bridge deck and torching the rebar to expose the girders. Using boom lifts, a team secured rigging from a 550-ton crane while excavators broke the girder ends free. Once detached, the crane lifted each girder and placed it in a designated stockpile area for further removal.

Scope of Work:

• Bridge Deck Slotting & Rebar Torching – Exposing girders for removal
• Heavy Equipment Operation – Boom lifts, excavators, and crane for precise demolition
• Rigging & Lifting – Secure placement of girders for further breaking
• Safety Execution – Working over an active highway with strict safety protocols

This complex demolition required careful planning and expert coordination to ensure safe, efficient removal of the bridge components without disrupting the active highway.
