Victoria Bridge in Riverside, CA

Built in 1928, the Victoria Bridge crosses the Tequesquite Arroyo in style. This bridge was built to carry streetcars on Victoria Avenue across the arroyo as well as auto and horse carriage traffic. It is a rare example in Southern California of an arch bridge of this magnitude crossing a generally dry location. The deck and railing were restored in the early 2000’s to their original 1920’s appearance.

Victoria Avenue in the Riverside area itself is a rather beautiful roadway to travel. It was constructed in the early 1900’s as such a roadway and retains most of the original features today, south of this bridge. Quite a few miles of the roadway are comprised of a two-lane divided roadway surrounded by orange groves. These orange groves comprise some of the last remaining groves in Southern California. It is significant as the Riverside area was home to the original orange groves that were planted in the late 1800’s in Southern California.

Park Blvd Traffic Update

While the buses aren’t running yet, most of the major changes to Park Blvd are complete. There are two new signals, one at Howard Ave and another at Lincoln Ave. At Howard Ave,  left turns onto Park Blvd are now allowed.

At Polk Ave, things are a bit different. Polk Ave is now blocked at Park Blvd,  with only a pedestrian signal in place. To get past Park Blvd,  use Howard or Lincoln. Left turns from SB Park Blvd are also now allowed onto University Ave.

Sharrows have also been added to Park Blvd as a part of this project. They run from near Cypress Ave to El Cajon Blvd. These changes have made bicycling and walking around the area much easier. While it was at the loss of the historic aspects of the roadway, it is an overall positive change. Please be aware of these changes and adjust your trips accordingly.

Old US 99 in Colton, CA

Realigned sometime in the 1930’s, the original alignment of US 99 is still visible near the intersection of Valley Blvd and Pepper Ave. Little remains of the original paving of US 99 through the Los Angeles area, so this is a special section.

Around late 2007, Valley Blvd was again realigned to better accommodate traffic at the I-10 interchange. Sections of the 1930’s paving are now sticking out from under the asphalt.

What is a “Sharrow”?

Sharrows. I’m sure you’ve seen them. Perhaps you’ve even heard about them. What do they mean? A “sharrow” or Shared Lane Marking is a newer addition to roadway striping. They are designed to be along major bicycle routes where a bicycle lane is impractical. The markings show that motorists should not only expect to see cyclists but they should also be further out in the lane.

The rules behind these markings are fairly simple. They must be 11′ from the curb and beyond the “door zone”. These sharrows cannot be on roadways with a speed limit greater than 35 mph, though there are some exceptions such as Park Blvd through Balboa Park, which is signed as 40 mph. When a roadway is not marked with sharrows, the rules are still the same. According to the California Vehicle Code (CVC 21202(a)), a cyclist doesn’t always have to ride to the right side of the roadway. The term used is “as far right as practicable”. This means that if roadway conditions warrant, a cyclist may travel away from the right side. When a roadway is marked with sharrows, cyclists should ride with the tires lining up with the arrows.

So, Sharrow or no, a roadway must be shared with cyclists.

Road Building in San Gabriel Canyon

In the 1930’s, Los Angeles County began construction of an additional roadway over the San Gabriel Mountains via the East Fork of the San Gabriel River. About half of the roadway, complete with with four larger bridges and a tunnel, was constructed. Work had progressed as far as “The Narrows” by 1938. However, the March 2-3, 1938 storms caused much of the roadway to be washed out. The project was then abandoned, leaving a large arch bridge stranded many miles upriver. The tunnel still exists as well, just north of the “Bridge to Nowhere”, though it has been sealed at both ends.

In the 1955,  a new road building project commenced in the canyon. This new alignment would stay high above the canyon floor until it got nearer to the “Bridge to Nowhere”, allowing that earlier work to come to some use. Progress on this roadway was slow, mostly due to poor funding. Convict labor was used for most of the project, similar to many other road building efforts at the time in Los Angeles County. Two tunnels were constructed as well. These still exist and are mostly intact. This project too was cancelled in the late 1960’s, leaving another large scar in the canyon. This road is presently known as Shoemaker Canyon Road.

Today, the canyon is protected from future development through the Sheep Mountain Wilderness Area. Even without this protection, the geology of the canyon makes for a very expensive project. Maintenance would also be costly, as seen with State 39 through San Gabriel Canyon and above Crystal Lake. In time, all these structures and cuts will wash away, leaving the canyon with only bits of concrete and asphalt to show what was once here.
