Road Sign Math welcomes McKenzie Myers to the game with this very first sign.

The math on this sign is great. Straight down the right hand side!

This sign is on US-97 heading southbound between Bend and Klamath Falls, Oregon. See sign on map!

Roger Knowles brings another sign from Oregon. This sign is in english, believe it or not. How great would it be to be able to tell people to get off on Clackamas to come to visit you?

Great math here, almost as great as the names in the sign.

This sign I-205 southbound in Portland, Oregon. The GPS coordinates are approximately N45.41063 W122.57225. See sign on map!

Ed.: With this run of four signs Oregon blasts onto the scene and immediately puts itself in 5th position in the state competition.

Roger Knowles puts another mathematically significant roadsign up for Oregon. This sign comes on the overpass of what may be one of the oddest names for a street we’ve seen — Going Street.

Nice math in this sign.

This sign I-5 northbound at Going Street in Portland, Oregon. The GPS coordinates are approximately N45.55515 W122.67837. See sign on map!

Roger Knowles brings another gantry sign from the interstates of Portland. Oregon seems to have a thing for these signs 1 mile apart.

The math is very obvious on this one.

This sign I-5 just after broadway in Portland, Oregon. The GPS coordinates are approximately N45.54069 W122.67138. See sign on map!

Roger Knowles extends our string of new state introductions with Oregon coming onto the map.

This gantry brings together two signs and makes the math work like peanut butter and chocolate.

290 – 1 = 289

This sign I-5 northbound just north of the 205 exchange in Oregon. The GPS coordinates are approximately N45.37798 W122.75386. See sign on map!
