Do you mean the entire Interstate 95 (the East Coast route) or just the stretch in a particular state?
If you mean the whole route: planning started before the Interstate era, but construction under the Federal-Aid Highway Act of 1956 began in the late 1950s. Major building continued through the 1960s–1980s, and the last long-standing gap was finally closed in 2018 (the I‑95/PA Turnpike interchange and rerouting in September 2018). So from the 1956 start to that final connection is roughly 62 years; from earlier planning in the 1940s it's about 70+ years.
If you want a state-by-state construction timeline or key milestones, tell me which state or what level of detail you want.
