The document discusses three projects along Rock Prairie Road: rehabilitating the east side pavement, expanding the overpass, and widening the west side. For the overpass, $4.6 million was allocated for adding a lane and multi-use paths. Design will be completed in January 2013 and construction will begin in spring 2013. Widening the west side is in the 2008 bond and traffic data collection was done in 2011. Design funding is included for 2013 and construction will follow the overpass work.

1. City Council
Workshop
November 8, 2012

2. Rock Prairie Road Corridor
 East side pavement rehabilitation
 Overpass
 West side expansion

3. Rock Prairie Road East
 Heavy truck traffic contributed to pavement
degradation
○ Hydrocarbon trucks accessing wells
○ Sanitation trucks accessing the landfill
 Acquiring right-of-way for future expansion to
four-lane boulevard section
○ SH 6 to William D. Fitch
○ ROW width is between 118-feet and 115-feet
○ Acquiring 20-foot wide PUE

4. Pavement Condition

5. Thoroughfare Plan – East Side

6. Rock Prairie Road East
 Current traffic does not warrant a four-lane
boulevard section
 Rehabilitation project will reconstruct Rock
Prairie from Bird Pond to William D. Fitch
○ Two travel lanes
○ Asphalt pavement
○ Open drainage
○ No sidewalks
○ No raised medians
 Staff will bring a design contract to Council for
consideration in early 2013

7. Rock Prairie Road Overpass
 BCSMPO received $4.6 million in State
Proposition 12 funds from TxDOT
 BCSMPO voted to allocate the funds to the
expansion of the Rock Prairie Road Overpass
○ Addition of one travel lane (east bound)
○ 10-foot wide multi-use path on both sides of the
overpass
○ U-turn structures on the north and south side
○ Area lighting

8. Rock Prairie Road Overpass
 City is responsible for funding the engineering
design and environmental studies
 TxDOT will manage the construction of the
project
 Final plans will be submitted to TxDOT in
January 2013
 Construction will begin in the spring of 2013

9. Conceptual Layout

10. Rock Prairie Road West
 State Highway 6 to Wellborn Road
○ Four-lane Minor Arterial
○ General Suburban
 Adjacent land uses:
○ Single Family Residential
○ Parks
○ Medical Facilities
○ Schools
○ Churches
○ Commercial

12. Traffic Conditions
 Rock Prairie and Rio Grande are operating at LOS A
 Rock Prairie and Longmire are operating at LOS C
 Rock Prairie and Longmire and expected to operate
at LOS D in 2013
 Challenges at the Longmire Intersection:
○ Traffic signal spacing
○ Land use generates high traffic volumes
○ Numerous left turns/driveways
○ Vertical deflections for drainage

13. Longmire Intersection

14. Rock Prairie Road West
 ROW acquisition for the widening of Rock
Prairie Road West was included in the 2008
Bond Authorization
 Collected traffic data in 2011
 Traffic model considered the following:
○ Barron Road Overpass
○ Barron Road East/Lakeway South
○ New development at SH 6 and William D. Fitch
○ Anticipated traffic from Scott and White Hospital

15. Conceptual Layout

16. Rock Prairie Road West
 Land acquisition is in progress
 Funding for design is included in the FY2013
capital budget
 Construction of the Rock Prairie Road West
project is expected to immediately follow
the overpass construction

17. Conclusion
 Three important projects in progress
 Construction on the overpass to begin in the
spring of 2013, and expected to take 12-
months to complete.
 Staff will request Council approval for
design contracts for the improvements to
the east and west side of Rock Prairie Road
in early 2013

18. East Side Acquisition
