Morphology

raceway = race + way (semi-transparent) = race + way

Although the form is clearly 'race' + 'way', the sense 'race' = fast current is specialized/archaic so learners may not derive the water-channel meaning from the familiar competition sense.

Etymology

Raceway can also mean a channel for water, because race once meant 'a fast stream' or 'rush'. That is why a raceway is a narrow water path that directs fast water to a wheel or turbine.
