505 / 506 Eastern Extension

505 / 506 Eastern Extension (French: l'Extension de la Ligne 505-506 à l'Est; Traditional Chinese: 505 / 506 東端延綫) is a railroad project by The Linx. The project will involve in extending the 505 / 506 Corridor Line eastward for 17.6 km along the existing Highway 505 rail corridor, adding 7 stations in the borough of East Archemedes and the Town of Donsley of the Regional Municipality of Gravenhurst. The project was first gazetted in 2015, and was delayed as the construction of East Archemedes CBD was progressing slower than anticipated.

The extension is an important cornerstone for the development of a new central business district (CBD) in East Archemedes. The extension will facilitate the growth of a community with 50,000 jobs and a population of 110,000 in the next 30 years.

Groundbreaking ceremony of the line was held on 23 January 2017. The extension is anticipated to complete by late-2019 or early-2020.

The project will cost 1,110 million Nichs.
