- Talisa Maegyr: "What if I told you my father sold lace on the Long Bridge and my mother, my brother, and I lived with him above our shop?"
- Robb Stark: "I'd call you a liar."
- Talisa Maegyr: "Not very noble to accuse a lady of dishonesty."

The bridge is so large that it is covered in rows of multi-level buildings, taverns, brothels, and marketplaces, forming a small neighborhood of the city unto itself.
When Robb Stark refers to Talisa Maegyr as "lady," she wonders how come he believes her to a member of the nobility. It is obvious to him and she poises a hypothetical question about what if she was a merchant's daughter who had a shop on the Long Bridge. Robb still remains firm that she is a noblewoman and she later confirms that she is.
Upon their arrival in Volantis, Tyrion Lannister and Varys explore the Long Bridge when the former insists on being allowed out of the carriage they've ridden in since departing Pentos. They view various shops and see the severed hands of thieves on display. They duck into a brothel after a Red Priestess unnerves Tyrion with her sermon.
Behind the scenes
The famous Roman bridge of Córdoba in Spain was used as a stand-in for the Long Bridge of Volantis - though the real bridge was then augmented with CGI to make it look proportionately larger and to add buildings and markets atop it, as the Long Bridge is described in the novels.
In the books
In the A Song of Ice and Fire novels, the Long Bridge joins the two halves of Volantis across the mouth of the Rhoyne. It is a great span with a road supported by massive piers that the Valyrians built at the height of their glory. Its gateway is an arch of black stone carved with sphinxes, manticores, dragons, and other strange beasts. The road is just wide enough for two carts to pass abreast. Buildings rise on either side of the roadway. One can buy almost anything in the shops on the Long Bridge.
In the center of the bridge the hands of thieves and the heads of executed criminals are displayed, with signs underneath stating their crimes (the severed hands and signs indeed appeared on-screen when Volantis was first seen in Season 5): "At the bridge's center span, the severed hands of thieves and cutpurses hung like strings of onions from iron stanchions along the roadway. Three heads were on display as well—two men and a woman, their crimes scrawled on tablets underneath them." (A Dance With Dragons, Tyrion VII)
The Long Bridge is one of the known world's most famous megastructures. Lomas Longstrider included it in his list of the nine Wonders Made by Man. Other wonders in this list include the Wall in Westeros, the Titan of Braavos, and the great triple walls of Qarth.
