It was a long time coming, but the final section of the Conception Bay South bypass road finally opened to traffic Wednesday.

Vehicles lined up to try out the new 5.6-kilometre stretch that connects Kelligrews and Seal Cove.

Work on extending the existing bypass road - which links Conception Bay South with Mount Pearl and St. John's - began in late 2009, but was ultimately delayed due to other, more pressing projects, said Transportation and Works Minister Nick McGrath.

The original completion date for the $25.3-million project was late 2011.

But McGrath was quick to note the bypass road won't necessarily end at Seal Cove.

"Well, it could always go on forever," he said. "The more economic growth that we have, we hope that we'll continue to see the economic growth. And if that's the case, then you'll continue to build highways to accommodate that."

Conception Bay South MHA Terry French noted the history and planning of the road goes back almost 30 years.

"John Buck, the minister of environment of the day, who was the MHA for C.B.S., cut the first piece on Manuels Bridge," French said Wednesday.

"And I remember visiting his house some years after and seeing (the scissors) in a plaque on the wall. And I said to him, 'you have to give me those scissors!' "

French used the same scissors to cut the ribbon on the new section to Seal Cove on Wednesday.
