Nineteen-year-old Dylan Murphy from Gretna had been walking on the motorway north of Carlisle in the early hours of Saturday February 23 when the collision occurred.
He was taken to the Royal Victoria Infirmary in Newcastle in a critical condition and died as a result of his injuries on Friday March 1.
In a statement released through Cumbria Police, his family this week said: “Dylan was a wonderful son who will be sorely missed.
“He was funny, and had a magnanimous personality. He drew people in wherever he went.
“He leaves behind a heartbroken mum, dad, sisters, partner, son, nan, uncles, aunts and many, many friends.”
A minute silence was held at Raydale Park ahead of the AFC Gretna v Gretna 2008 local derby game on Saturday in memory of Dylan, who was a close friend to many of the players.
Hundreds of his friends took to social media to pay their own tributes to the teenager.
One described him as a “a lovely boy taken far too soon”, while others said he was a “great dad” who was “a pleasure to know.”
Dylan’s funeral will take place at Roucan Loch on Wednesday March 13 at 11 am.
A green balloon release has also been organised in his memory, which takes place at Gretna football field this evening.
Meanwhile, Cumbria Police are still appealing for information in relation to the incident.
A spokesman said: “Anyone who witnessed this incident, and has yet to contact police, is asked to get in touch referencing incident 40 of February 23 2019.”
