Prior to New Berlin becoming a City, Coffee Road was known as Coffee Street. Coffee Street connected Racine Avenue with Mukwonago Road (now National Avenue) and was a one track gravel road which passed through a German neighborhood and Little Grove School District. Passersby would stop along Coffee Street to sample their neighbor's coffee bubbling on the back of each home's big black stove. To recognize the historic and cultural heritage of Coffee Street for the education, inspiration, pleasure and enrichment of the citizens of the City of New Berlin, decorative signs referencing the historic nature were placed below the existing Coffee Road signs.
