Produced as a cooperative effort between the City of Allen and the Allen Parks Foundation, Market Street Allen USA Celebration presented by Texas Health Allen is Allen’s largest and most spectacular community event to say the least! Centered around the theme of being “First to the Fourth,” Market Street Allen USA serves as the community’s Fourth of July celebration, uniquely held the last Saturday of June every year. The 2017 Market Street Allen USA Celebration will begin at 4 p.m. on June 24 at Celebration Park. Being the last Saturday in June allows the event to be a stand out among area cities’ celebrations and promotes attendance locally, regionally and statewide.
