Overall Objective
Integrate the Berry Bridge and Northern Interchange structures and earthworks within the landscape of northeast Berry. Berry Bridge - Urban Design Principles
- Develop bridge architecture that complements the pastoral setting.
- Maximise retention of existing screen landscape.
- Minimise bridge piers and profile.
- Keep undercroft areas open, ventilated and with access to light.
- Maintain a consistent bridge profile without awkward junctions,
steps or faceting.
- Explore opportunities to reflect the unique character of Berry
and the Shoalhaven.
- Utilise locally sourced stone for abutment linings and scour protection.

Berry Bridge Sketch Alternative 1
- Prestressed concrete planks (15m span)
- Integrated headstocks
- Cost effective rectilinear frame support.
Typical Cross Section Elevation at Pier
SLIDE 30
Advantages:
- Smoother vertical curve/less faceted
- Thin profile
- Attractive integrated support piers
- Cost competitive overall
Disadvantages:
- More columns, closer together
SLIDE 31
Berry Bridge Sketch Alternative 2
- Super ‘T’ concrete beams (35m span)
- Integrated headstocks
- Headstock recessed in depth of beams
- Cost effective rectilinear frame support
Typical Cross Section Elevation at Pier
SLIDE 32
Advantages:
- Attractive integrated/recessed support piers
- Less columns than with Planks
Disadvantages:
- Less columns than with Planks
- Faceting of vertical curve may cause difficult junctions

Northern Interchange - Urban Design Principles
- Minimise the visual presence of interchange structures.
- Minimise impacts on existing properties and access.
- Minimise the interchange footprint.
- Retain mature trees along the highway.
- Consider the sequential views on the northern approach.
- Contribute to the township arrival/departure experience and to legibility.
- Develop Berry township entry signage strategy.
- Frame rural and township views from elevated vantage points.
- Relocate Berry Memorial sculptures.
