The bridge over the Mass Pike on Brookline Avenue will be named the Big Papi bridge and the road connecting Fenway to the new commuter rail stop will be named David Ortiz Drive.

Former teammates took to the field hoisting the World Series trophy, a reminder of those who helped end the curse.
When it was finally Big Papi's turn to talk, his goodbye was as classy as ever.
"I wanna thank my mom ... I wanna thank you, Mom, wherever you are. I love you so much and I miss you," he said.
Then, one more tip of his cap to Red Sox nation.
"I want to thank all of you. The fans -- thank you, thank you so much ... You guys are the best," he said.
And with that, it was the end of Big Papi's regular season with the Red Sox, but certainly not the end of his legacy.
