The Boston Strong message will be featured to runners at the 25.5 mile mark.
A "Boston Strong" message was painted on an overpass along the Boston Marathon course as one of the race's newest landmarks.
Boston mayor Marty Walsh, Massachusetts governor Charlie Baker and Boston Athletic Association executive director Tom Grilk were on hand for the ceremony at the Bowker Overpass which spans over Commonwealth Avenue and Charlesgate West. The overpass is located on the 25.5 mile mark of the course.
The message is painted in the race's traditional blue and yellow colors. The two words became the city's motto after twin bombings near the amrathon's finishi line killed three people and injured more than 260 others. MIT police officer Sean Collier was a fourth victim after he was shot and killed by the marathon bombers.
The 2016 Boston Marathon will take place on April 18.
