Frontage Road Numbering Systems?

[texaskdog]

When I lived in Newport News VA I HATED the frontage roads they had in the region.  Some were unidirectional, matching the main lanes and some were Bidirectional  I was stationed at Langley AFB and they used to make a big point of warning incoming personnel because we would regularly have head on collisions when someone either went the wrong way on the unidirectional ones or forgot it was bidirectional and used the oncoming lane as a second lane

in Texas, one has bidirectional frontage roads on which traffic going against the mainline direction has to yield to off-ramp traffic.  that just seems like a terrible thing waiting to happen.

They are usually in the more rural areas though for residences or places where there aren't exits every single mile to be able to loop back around. East Texas on I-20 has many spots like these.

Also Texas toll roads usually have the Texas Toll signage for the mainline and a Texas State highway on the frontage roads. Sam Rayburn Tollway and TX 121, PGBT and TX 190/TX 161. Can't remember if the same is true for Sam Houston Tollway/Beltway 8 in Houston. For the most part Texas upgrades and widens existing roads then turns them into freeways or tolls.

There's a thread somewhere talking about some of these for Texas.

Actually driving on the frontage road when you get to a yield sign and realize just how fast the freeway traffic is coming, you watch out.  Just assume you're going to be hit, like when riding a bike at night or driving the golf cart through the parking lot at church...they won't see you.

the tough part is attempting to judge which traffic is staying on the freeway, and which is exiting.  it's tough to do that with much advance notice, as cues like brake lights and turn signals are missing.

The frontage roads in Tulsa along I-44 are known as "Skelly Drive" which is also the name of I-44 itself.

according to my GPS, the frontage road for "Pacific Highway" here in San Diego is "Pacific Hwy".  oh, that was a beast to figure out.

The frontage roads for Fordham and Preddy Boulevards (I-40 and I-85) in Greensboro also have those names.

In New York City, where we call them "service roads", most of them are named the same as the highway they run along. Fortunately, on street signs they have a directional suffix appended to differentiate them - e.g. "Hutchinson River Parkway East". It should be noted, however, that the direction is not the direction of travel. Rather, it is the location of the service road in relation to the highway. So, for the Cross Bronx Expressway, which runs generally east-west, the service road on the westbound side is "Cross Bronx Expressway North". The fact that this happens to correspond to I-95 southbound might potentially be confusing to someone who doesn't know better.

Some exceptions to the naming rule exist where the service road retains the name of a road that existed prior to the highway on that alignment:
- Bruckner Boulevard (Bruckner Expressway)
- Astoria Boulevard (Grand Central Parkway)
- Conduit Avenue (Belt Parkway)
- Narrows Road (Staten Island Expressway)
- Gannon Road (Staten Island Expressway) (Where's Link when you need him?)
- 7th Avenue (Gowanus Expressway)

In Houston, the most known is Sam Houston Tollway and beltway 8. That is more due to the toll road being a Harris County road and the frontage road being a TxDOT road. The only sections built by the TxDOT are the free sections from I-45 to US59 for the airport. And from US90 to I-10 for the ship channel bridge. The other toll roads that have frontage names and maybe numbers due to a FM being in the area. Westpark Tollway has Westheimer as its "frontage" road, but that is due to it being built right between FM1093. Hardy Tollway is build next to Hardy road/East Hardy Road, and the Hardy rail line.
