2. Minimize Disturbances
 Reversible Lanes
 Moveable “zipper” barriers
similar to I-15 HOT Lanes
 Change lane assignment
based on traffic patterns
 Adds extra lane of capacity
without construction

3. Access and Mobility
 Signal Coordination
 Innovative Intersection design
should be analyzed.
 Continuous-flow
intersections
 Diverging diamond
interchanges
 Single-point urban
interchanges
 Roundabouts

4. Multi-Modality
 Improve Park-and-Ride
facilities
 Bike lanes should be
designed, built and
striped

5. Livability
 Shared-Use Path following Williamson Creek
 Enhance pedestrian
and bike access
 Encourage alternative
modes of transportation
 Improve access to and
attractiveness of
Williamson Creek corridor

6. Livability
 Sound Absorbing Walls
 Panels filled with High-Density Polyethylene

7. Aesthetics
• Use the
overpasses as a
canvas for local
artists
• Helps to “Keep
Austin Weird”

8. Aesthetics
 Musician-themed
Overpasses
 Live Music Capital
of the World

9. Aesthetics
 Artwork Under
Williamson Creek
Bridges
 Example: I-35 over
San Antonio River

10. Solar Powered Electronic Toll Collection
 Long-term energy
cost savings
 Environmentally
friendly
 Solar panel
lifespan of 20-30
years

11. Interlocking Concrete Pavers
 Road shoulders, bicycle
and pedestrian paths.
 Benefits:
 Reduces storm water runoff
 Decreases urban heat island
effect

12. Storm Water Management
 Grass Swales
 Low cost, low
maintenance
 Increased storm
water infiltration
 Bioretention Cells
 Removes pollutants
from runoff

13. Lighting
 LED Street Lights
 Can use stored solar
energy
 Save 50-70% on
Energy Costs
 Extended lifespan

14. Use Local Materials
 List of Possible Locally-Sourced Materials:
 Construction materials
 Technology Vendors
 Native Plants
 Hill Country Granite
 Benefits:
 Supports local economy
 Reduces transportation costs
 Reduces fossil fuel use and greenhouse gas emissions
