DATE: September 6, 1990
SUBJECT: Speed Zone Investigation
LOCATION: McNeil Rd. from South Blair Street to the City Limits
Date(s) of Previous Investigation:
A Traffic Engineering Investigation has been conducted to determine the maximum speed limit on
McNeil Road from just west of South Blair Street to the city limits (west). The following
information was collected and analyzed

Note: Current speed limit to the East of the study area, which is the statutory 30 MPH, is not
posted. Current speed limit to the West of the study area is 45.
* Segments shown on Exhibit "A".
-9 1. 1 I 11_L!_'JWTir1KOMHTrMTTr1ff = 1. 1 1' 11
Eastbound (city limits to I-35) — vacant (railroad), with two intersecting "T" streets from the
south.
Eastbound (I-35 to South Blair St.) — vacant (railroad).
Westbound (city limits to I-35) — Commercial/Industrial multi -family for .4 miles west of I-35.
These uses are served by 8 driveways. The remainder is back on single family development and a
church. There are total of 7 driveways serving these uses.
Westbound (I-35 to South Blair St.) — Vacant land except for Public Works building, served by
one driveway onto McNeil Road.
3 - Road Surface Characteristics. Shoulder Conditions
Four lane paved with curb and gutter east of Oakridge and two lane paved rural section west of
Oakridge.
4 - Grade and Alignment
Straight and level.
5 - Sight Distance
Excellent.
6 - Safe Sneed for Curves or Hazardous Locations n Within the Zone
* The transition of the four lane facility into a two lane rural section facility west of Oakridge
creates a hazard.
* The intersection of County Road 172 and McNeil Road is heavily used and creates a
hazard.
* The transaction of McNeil Road into a local city street (Blair Street) includes a
grouping of curves and intersections which require special attention.
7 - Parking Practices and Pedestrian Actiyiu
Sidewalk on north side of road.
No parking observed on street.
8 - Accident History
Report Accident Experience for 12 -Month Period Ending 12/30/89:
There were 14 reported accidents on this section of McNeil Road during the 12 month period
ending December 30, 1989. There was no significant concentration of accidents to a specific
location on the roadway.
General Comments
This is an arterial roadway with limited side friction; however, there are numerous turning
movements and no left turn lanes. In addition, there are numerous turning movements onto
McNeil from adjacent subdivisions.
The 85 percentile speed for eastbound traffic on the four lane section of this roadway ranges from
32 MPH to 44 MPH and averages 40 MPH. The 85 percentile speed for eastbound traffic on the
two lane section of this roadway ranges from 46 to 48 MPH and averages 47 MPH.
The 85 percentile speed for westbound traffic on the four lane section of this roadway ranges from
38 to 46 MPH and averages 42 MPH. The 85 percentile speed for Westbound traffic on the two
lane section of this roadway ranges from 46 to 48 MPH and averages 47 MPH.
The speed limit in the county west of the city limits is 45 MPH. Traffic slows near the intersection
of County Road 172 to 32 MPH eastbound and 38 MPH westbound. The necessity to provide
reasonably uniform speed limits would eliminate a special lower speed limit for the quarter mile
segment of McNeil at the County Road 172 intersection or a higher speed for the one-quarter mile
segment E -F.
The railroad crossing, at street grade, at McNeil road as it passes under I-35 can present a hazard
to motorists. However, this situation does not necessarily affect study speed limits since there are
railroad cross arms to stop traffic on each side of the crossing, and traffic control devices will be
erected at this intersection.
Finally, the two eastbound lanes of McNeil Road split at the eastern edge of the study area; at the
intersection of McNeil and South Blair Street. The northern most eastbound lane of McNeil is
required to turn onto S. Blair, while the southern lane continues as McNeil Road as it separates
again as it reaches the Mays Street bridge and the urban downtown area.
This street pattern requires eastbound traffic to make numerous turning movements on narrow
pavements while coping with other intersecting and converging traffic.
Prepared by:
James M. Stendebach,
Assistant Director of Planning and Community Development
City of Round Rock.
Based on the analysis of this information, it is my engineering judgement that the speed limit on
McNeil should be established as follows:
McNeil Road eastbound and westbound from the city limits to a point 400' west of Oakridge
should be 45 MPH; and McNeil Road eastbound and Westbound from a point 400' west of
Oakridge Drive to the east side of Lake Creek should be 40 MPH.
The current eastbound speed limit of 35 MPH, currently posted on McNeil Road at, or near, the
road's intersection with Lake Creek should be eliminated and the statutory to 30 MPH speed limit
should apply East of Lake Creek to more adequately prepare motorists to cope with the required
turning movements and intersection traffic.
McNeil Road, west of South Blair to 1-35, is a straight, four-lane, road with good sight distances
west of its intersection with South Blair St. The two study sections of this portion of the road
(between S. Blair and 1-35) have westbound 85 percentile speeds of 44 MPH and 36 MPH.
Therefore, it is recommended that the current westbound speed limit of 35 MPH, posted on
McNeil Road at or near its intersection with South Blair, be increased to 40 MPH.
