Excavate to remove obstructions for pile driving
Drive 8 steel H-Piles
Cover piles and re-open to traffic
14Phase II 4 Day Closure
Close bridge and detour traffic
Remove old bridge
Excavate to expose new piles and remove old
abutments
Cut pile to elevation and place prefabricated
abutments
Backfill and stabilize slopes with riprap
15Phase II 4 Day Closure
Erect 10-65 pre-cast pre-stressed concrete box
beams

18Development of the NEXT beam
- Why Develop a New Bridge Section?
- Box Beams have limitations
- Accommodation of Utilities
- Difficult Fabrication Process
- Multi-step process
- Difficult Field Process
- Grouting of Joints
- Post-Tensioning

21Development of the NEXT beam
High Level RR Platform Beam
22Development of the NEXT beam
23Development of the NEXT beam
- Depth 24 36 in 4 increments
- Typical Span Range 50 85
- Width will vary 8-0 12-0
- Used for bridges with utilities
- Works very well for Accelerated Construction.
24NEXT Beam Adjustable Width 8 to 12
25NEXT Beam Combinations
