Texas Frontage Rds

DO NOT ADD SHIELD TO FRONTAGE RD

Naming

This is guidance for primary and alternate name(s) for Frontage Roads. Important to remember that those using Apple CarPlay or AndroidAuto do not get editable visual turn instruction therefor, choosing primary segment name is very important. We hope that in the future visual turn instruction will work in Apple CarPlay or AndroidAuto.

Primary Name

Primary name should match street signs and/or freeway name if present. We don't want the primary name of the frontage road to change at every intersection. Primary name should only change if the frontage road changes which road it parallels or the named freeway it parallels is no longer named. It is important to review the entire juistiction that named that fwy, city or county, to see exactly where fwy name ends. The primary name for Frontage Road should always have Frontage Rd on end. Also do not add Cardinal Directions unless they are used in green street signs.

If Fwy / MH is shared between two shielded roads, use primary XX-XX in primary name same as National Guidance for Concurrent names

Lyndon B Johnson Fwy Frontage Rd

Parallels I-635 in Dallas County. Street signs for turns onto Lyndon B Johnson Fwy's Frontage Rd commonly say I-635 LBJ Fwy or LBJ Fwy or I-635 Lyndon B Johnson Fwy. It is common knowledge that LBJ= Lyndon B Johnson and so in Waze we spell in out so TTS will work.

US-175 Frontage Rd

Parallels US-175 in Dallas County. Small green street signs for turns on to US-175 Frontage road commonly say N Highway 175. It is common in Texas for small green street signs to spell out US Numbered Highways. It is common knowledge that N Highway 175=US-175.

Katy Fwy Frontage Rd

Parallel I-10 in Harris County. Small green street signs normally say IH-10, but it is very well known that I-10 is Katy Fwy. We will fix the discrepancy between street signs and Waze in VIO and TTS.

US-290

Parallels SH-290 Toll in Travis County. If Frontage Rd is a highway itself different then freeway it parallels should be named same as national guidelines for US Numbered Highways. As to not mess with Big Detour Prevention Mechanisms we leave these as is. Do not add Frontage Rd on the end.

SH-121

ADD GUIDEANCE

I-14 Frontage Rd

Frontage Roads that do not have a name or signage does not exist or signage is Frontage Rd should be named “XX-XX Frontage Rd” XX-XX being the shielded road it parallels.

Guidance	Example
Lyndon B Johnson Fwy Frontage Rd
US-175 Frontage Rd
IH-10 Frontage Rd
US-290
SH-121
I-14 Frontage Rd

Alternate Names

Alternate names are very important for destinations and addresses that reside on the Frontage Rd. We want to make sure not to add an alt name that matches the road it parallels. Please refresh your knowledge on the Detour Prevention Mechanisms.

USPS cities

• Address match
  • GIS
  • Business websites
  • USPS
    • If address is IH-XX or N Interstate XX
• If named fwy add XX-XX Frontage Rd (Primary for adding Places in app, easier to recognize)

Ramp Name

Road names#Local freeway names and significant bridges

Not sure if this following section is needed as it’s already national guidance

If named Fwy add • Fwy Name

“to I-635 N • Lyndon B Johnson Fwy”

Fwy Name

“I-635 N • Lyndon B Johnson Fwy”

Example pictures of SV / signage or lack there of:

US-290 / SH-290 “Austin”

I-20 “Dallas”

I-14 / US-190 “Killeen”

Visual Turn Instructon

Should be added added to all public street turns onto frontage road. PLR turns for example not top priority. Over passes and major intersections higher priority than side streets.

Visual instructions Box should match naming guidelines above but replace numbered highway with its shield.

Visual Instruction Box could be made of up two or three components

Check with street view or BOTG to verify what signage actually says

Roadway Shield Plus Fwy Name (if applicable) or Local Street Signs Plus Frontage Rd
