I googled "What is the difference between a trestle and a bridge:

A bridge is a structure that connects two or more points allowing access across railways, rivers, streams, ravenes, etc., whereas a trestle is a framework structure that some long bridges are built upon. That framework consists of vertical, slanted and cross peices that are used to support the bridge.

Trestles are similar in nature to viaducts except for the fact that viaducts consists of a number of short concrete or masonry spans supported by piers or towers and not what was described in the previous paragraph.

A bridge with a trestle is technically referred to a "trestle bridge," but it's usually referred to simply as trestle!

So now we know; a "trestle" is a type of structure used for some bridges. 😏

I noticed a sign by the trail about the bridge but didn't stop to photograph it.

It only took a moment to actually google Riverside Train Bridge, and it turns out to be rather historical. I may have to put a little effort into some more serious photography of it.

About the URL, note that raincross is the name of the local symbol for Riverside:

About the Raincross Symbol
The unique City Raincross Symbol is derived from combining a replica of the mass bell used by Father Junipero Serra, missionary priest and founder of the California Missions, and the cross to which the Navajo and Central American Indians prayed for rain. Called the "Raincross" symbol, it was designed for the Mission Inn and given to the city by Frank Miller. The Raincross symbol has been identified with Riverside since 1907. Variations of the symbol are used extensively throughout Riverside in architecture, street signs and lighting standards, and is used on the City flag.

Playing on the nostalgia for the state's Spanish heritage and the romanticized images of the missions and the Indians portrayed by Helen Hunt Jackson in her novels, Miller, Matthew Gage, the Sunkist Cooperative, the Santa Fe Railroad and other city boosters worked together to market Riverside as a Spanish Mediterranean Mecca. Riverside's climate and landscapes continue to evoke this Mediterranean paradise. There is a strong community support for historic preservation for a city that reveres its past and has built on that firm foundation.

   It's possible that trestle is a more specific type of bridge, but I've usually 
heard the term used in conjunction with trains.  It could just be that that's how 
they were constructed at home
