Highway Tour Coming in April

I am putting together another highway tour, this time in San Diego County. On April 28 (weather permitting), I will be hosting a tour of US 80 from El Cajon to the Desert View Tower. Various stops will be made along the road at important locations, including the Wisteria Candy Cottage and the Desert View Tower. If you’re interested, please RSVP prior to April 25th. There will be no cost for the tour as well. I look forward to seeing you all out there on the highway. More details will follow as the tour gets closer.

New Ridge Route Website

Recently, I became a board member of the Ridge Route Preservation Organization. This group is dedicated to helping preserve and promote the historic Ridge Route in southern California. One of the first things I have done as a part of this group is to create a new website for the group. This site is an offshoot of the “RidgeRoute.Com” site, hosted by Harrison Scott. The new site will give updates on the progress we make regarding the roadway as well as any other news pertinent to the Ridge Route. Come take a look at “http://ridgeroute.org“.

Highway Tips #2 – Signs

Road signs come in many different sizes, shapes, and colors. Each one carries a specific meaning to help guide you down the road in a safe manner. This installment will discuss each of the types of signs and what they mean. Road signs come in a variety of colors. Each color has a meaning, which can be quite important to know. The colors run from red, yellow, white, blue, green, brown, and orange.

Red signs mean something is prohibited. Only a few signs use this color – stop signs and wrong-way signs are the most common of these. Stop signs are also the only one that is octagonal. The color red was not the first choice, however. Stop signs used to be yellow with black lettering. Color might depend on where you were. Eventually, stop signs became standardized with a red background and white lettering. Yield signs and some no parking signs also use this color scheme. While yield signs don’t prohibit movement, they are there to warn you of opposing or side traffic.

Yellow signs are advisory or warning. Things such as upcoming intersections, curves, and other roadway hazards are generally marked with yellow signs. Curves are a good example of this. The speed signs at curves are advising you of a safe speed for the curve. They aren’t a speed limit for the curve. It is a generally good idea to travel at the advised speed. Depending on many conditions, you may be able to go faster that the posted speed. With this in mind, I have found that 25 mph seems to be a breaking point for curves. Curves posted at 25 mph or higher can generally be driven faster. When they are posted lower than 25 mph, slowing down is highly advised. I’ve seen speeds as low as 5 mph posted on some roadways. I’ve also seen speeds as high as 60 mph. A curve with that high a speed is not a problem, but may be in an area with few curves and it is nice to know you don’t have to slow for it. Upcoming intersections are also posted with yellow signs. These signs tell you not that one is coming up but what type it is. Some signs are customized to show specific intersections, especially if it is a blind intersection in a curve.

Black and white signs are regulatory signs, meaning they show some sort of rule that must be obeyed. Speed limit signs, for example, use this scheme. This is different than the curve advisory signs, which also show speed, as these signs show the maximum limit, not the advised limit. Parking signs are also generally in black and white as they limit or restrict parking in an area. Other signs in this category include bike lanes, passing, and other signs restricting either the movement or type of vehicle allowed in an area or lane.

Next services sign in Utah, which are located in Hinckley.

Blue signs are very specific in use. They act as guides to hospitals, telephones, and where services can be obtained. Roadside services can include gas stations, food, and lodging. These signs can be quite helpful for roadway users that are unfamiliar with the area and are not sure what sort of services can be obtained at a particular exit. Use of these signs varies by state as well. Some states show specific businesses, where others are more general, e.g. “Gas, Food, Lodging – Next Exit”.

Green signs are also guide signs. These give directions, by use of an arrow, to locations such as cities and roadways. They also give mileage to locations along a route. On freeways they generally show distances to the next exit, where others show distance to the next three cities. They may also mark things such as bike routes, which are roadways where there is no marked lane specific for bicycles but may be easier for bicycling in general.

There are also brown signs which mark recreation and historic area, such as beaches and parks. Park lands, such as national monuments, are marked with brown signs as well as forest areas. Beaches, such as the various State Beaches along the coast are marked with these brown signs as well.

The last signs covered here are orange. These are for construction areas. These signs perform a wide variety of tasks but always mark a construction area. These are to be heeded in part to ensure the safety of construction workers. Detour signs also use this color scheme and mark an alternate route in case the main route is closed. Always use caution in areas marked with orange signs. In addition to construction workers, roadway quality may greatly vary as well. Well-paved roads may be turned to dirt for a time during the construction and speeds may be greatly reduced from normal.

As you can see, road signs come on many shapes and colors. Each help roadway users get to their destination in all sorts of ways. So, next time you’re out on the road, keep this in mind and it may help you on your journey to wherever you may be going.

Highway Tips – Roadway Striping

This is the first part of a new series on SoCalRegion where we will discuss various topics related to roadways, their design, signage, as well as other features to help assist all road users in traveling throughout California. Many of these features exist in other states, but some have a different take on things.

Roadway striping comes in a few different colors and designs. Each of these have a meaning. Even without using signs, you can use striping to help determine what is going on with a roadway. Using these clues can also help aid with navigation in unfamiliar areas.

The Basics

Standard double-yellow striping

Let’s start with the basics. Two basic elements of striping are common throughout the United States – yellow means dividing opposing traffic and white means same direction of traffic. These colors remain nearly universal throughout all 50 states. Double striping, no matter the color, denotes a “no passing” or “no crossing” location. Passing, assuming the roadway is two lanes wide, can be done when the stripe on your side is broken. When the whole stripe is broken, both sides can pass.

Divided Roads

Two sets of double yellow stripes dividing a roadway

Multilane highways are divided in a variety of ways. When it comes to striping, there are three main types. The first is still the basic double-yellow striping. When a roadway needs a bit more of a divider, two sets of double yellow stripes are placed. These are considered “painted barriers” and are not to be crossed in any way. Some of these roadways have breaks in the striping, usually on one side only, to allow for turns onto side streets or driveways.

Common center turn lanes are another way to divide a roadway. These can exist even on two lane roadways but are more common on multilane roads. These center lanes are striped with a solid yellow line on the outside and a broken yellow line on the inside. These lanes allow both directions to make left turns.

Freeways

Freeways, while the striping is color coded the same way as regular roads, do have some different styles and meanings. Exit Only lanes, meaning lanes that will exit a freeway shortly, have something Caltrans calls – Elephant Tracks. When a lane is going to leave the freeway, the striping changes in thickness and frequency. These stripes are wider and a little more frequent than regular lane striping. It is one of the visual cues that is designed to help motorists determine if they are in the correct lane, regardless of signage.

Souith at the 163, the “Four Level” interchange in San Diego. Here you can see the transition to exit only striping for State 94 on I-5. Also note the change at the gore point for the shoulder striping.

At the exit itself, the shoulder striping in California has a unique modification. Designed to aid motorists in times of reduced visibility, the shoulder stripe has a break at the exit and flares out to mark the exit. In areas subject to heavy fog, there is an additional exit cue – reflectors. These are off to the side of the shoulder striping at intervals and are in rows of three, two, then one at the exit.

Where most freeways have only one HOV lane, this has two from Adams Ave south to I-105.
118 through the northern San Fernando Valley near Reseda Blvd.

HOV lane striping is another variation found on California freeways. Until a few years ago, these lane were, in general, striped with a double set of double yellow lines, acting as a painted barrier. There were variations based on available space as well. Specific entry/exit points where marked with broken white striping. These stripes are now being changed to double white lines with broken striping at the entry/exit points.

As you can see, there are many ways to determine what is going on with a roadway without looking at signage. Striping help guide road users in ways signage cannot. So, when you are in unfamiliar territory or in conditions where you can’t see the signs, use these clues to help direct you to where you are going. The stripes are there to help!

Highway Cleanup – October 8, 2017

Today, myself and three others cleaned my portion of I-8 and the western US 80 adopted sections. Temperatures were a bit warmer than planned, but still not that bad. A bit more of a breeze would have helped though. We all met at 9 am at Laguna Summit and started with cleaning I-8. There ended up being a bit more trash than I expected, which is ok for a first cleanup. We managed to fill six large bags with trash and left the highway quite clean. US 80, however, was much easier. What little was there only filled one bag halfway.  I do with to thank the volunteers for coming out. It was quite helpful and made the cleanup go fairly smoothly. I do plan another cleanup in a couple of months, this one will include I-8 and both sections of US 80 (Laguna Summit and Jacumba). Temperatures should be nicer by then as well.

End of the cleanup on US 80.

Adopt-A-Highway Cleanup – Sunday, October 8, 2017

On October 8, I am planning another highway cleanup. This one will be in eastern San Diego County and cover two sections of highway, I-8 at Laguna Summit (Sunrise Highway) and US 80. My section of I-8 runs from the summit to two miles east with about 1/2 of it able to be cleaned. The section of US 80 runs from just below Laguna Summit to two miles east as well. Both roadways should be a fairly easy cleanup. The plan, thus far, is to meet at I-8 and Sunrise Highway / Old Highway 80 at 9 am. Safety equipment, such as hard hats and vests will be supplied. There will be a safety meeting for all the volunteers as well before the cleanup begins. Bring plenty of water and snacks as we will be out there a while. Only those 18 and over can volunteer. Please RSVP as so I can get an idea of how many to expect. So, come on out and help clean some of our counties roadways.

New section of Adopt-A-Highway now signed!

I’m not quite sure when the sign went up, but it was most likely in the last few weeks. My newest section of Adopt-A-Highway, here in San Diego County, is finally signed.

New signage along I-8 eastbound at Laguna Summit.

Now that it is signed and I have a permit in hand, it is time for a cleanup. Unless temperatures exceed 85 F, I am planning a cleanup of the adopted sections of I-8 and US 80 in the area on October 8, 2017. If you’re interested in joining, let us know!

Help designate US 99 in Bakersfield as historic!

There is a group in Bakersfield trying to get historic route signs posted on the original alignment of US 99 through the Bakersfield area. They could use your support. Check out the site below for more information.
