Hayley Atwell reprises her role as Carter from the film series, and is joined by regular cast members James D'Arcy, Chad Michael Murray, Enver Gjokaj, and Shea Whigham.
The episode received praise from critics, especially the performances of Atwell, D'Arcy, and guest star Lyndsy Fonseca, as well as Russo's direction, and the inclusion of the fictional radio drama, the Captain America Adventure Program.
SSR Chief Roger Dooley assigns Agent Ray Krzeminski the task of sifting through the remains of a Roxxon Oil refinery that was imploded by one of the bombs while he and Agents Jack Thompson and Daniel Sousa visit Roxxon CEO Hugh Jones, who notes a rivalry between himself and Howard Stark (the creator of the molecular nitramene formula and a current fugitive from the law) and brings up Stark's work with Vita-radiation.
Dooley orders Thompson and Carter screen every Roxxon employee for Vita-radiation, in case the implosion was an inside job.
During the screening process, Carter recognizes scientist Miles Van Ert, who had created the weapons for the mysterious Leet Brannis.
Sousa finds a hotel key that belonged to the man in the green suit, and discovers a woman's footprints, not realizing that they are Carter's.
Back at the SSR, Carter is relieved that the other agents have no evidence of what she has been doing, but unbeknownst to her, Krzeminski finds the license plate for Howard Stark's car that she and Jarvis had taken to the Roxxon refinery.

[5] Eric Goldman of IGN gave "Bridge and Tunnel" a score of 8 out of 10, indicating a "Great" episode, praising the chemistry between Atwell's Carter and D'Arcy's Jarvis, Fonseca's performance as Angie Martinelli, and the "fun, retro–Alias vibe", while noting that the male agents "need fleshing out", and feeling that some of Carter's more slapstick humorous moments were "forced" and "out of character".
He concluded his review by stating "[Agent Carter]'s got the escapist joy that Marvel movies provide, but it's delivering them weekly instead of once every 6-8 months.
