Parts of a string into an array

I’m looking for a good way to grab the names, the colors, and the numbers from a string and place them in an array. Here’s the string:

El Norte Pkwy class=“green” 70 mph
Valley Pkwy class=“green” 59 mph
Auto Park Way class=“green” 65 mph
Felicita/Citracado Pkwy class=“green” 55 mph
Centre City Pkwy class=“green” 75 mph
Pom/W Bernardo Dr class=“yellow” 48 mph
Rho Bernardo Rd class=“yellow” 47 mph
Bernardo Center class=“green” 60 mph
Camino del Norte class=“green” 64 mph
Carmel Mtn Rd class=“green” 62 mph

The only way I know would be looping and finding white spaces but not sure how.
Any suggestions are much appreciated!
