According to a NewsLanc source deemed reliable, the $10 million is from the Capital Budget item inserted last July by Senator Gibson Armstrong. It apparently is for the extension of certain streets to open up the Northwest and reconnect it to the city. It is all part of the larger Northwest Gateway Project.
The source states this money will not be spent on the landfill or moving the rail yard. According to the source's information , PennDOT still has not decided whether to fund the $9 million for rail yard relocation this year.
