The idea of extending Newtown pike was an effort to move traffic out of downtown and increase traffic flow trying to get from the south side of Lexington to the north side.
The first part of the extension opened in September 2010 and is known today as Oliver Lewis Way.
But the project ran into a problem: families living in the Davis Bottom neighborhood had to be relocated.
Faced with the problem, officials came up with a plan to help move those families to new affordable housing.
City and state officials joined to together to break ground on Wednesday create the affordable housing for the residents and continue the expansion of Newtown Pike.
The new homes are scheduled to be open by this fall.
