four-laning from Parry Sound to north of Nobel. Later in 2005, the provincial government announced that four-laning between Parry Sound and Sudbury would be completed by 2017. The first project completed north of Parry Sound was the section between Sudbury and Estaire, which opened on November12, 2009. The section from south of the Seguin River in Parry Sound to north of Highway 559, bypassing Nobel, opened on October26, 2010. The former alignment in Sudbury is now known as Estaire Road, while the former route through Nobel is now Nobel Road. In 2008, work began to realign the S-curve at Highway637; two lanes opened to traffic on July27, 2010, while the completed four-lane route, with an interchange at Highway637, opened to traffic on August8, 2012. The former alignment now has the name Murdock River Road, and serves as a local road accessible only from Highway637. In the summer of 2012, the Highway69 designation was shortened by , between MacTier and 1kilometre north of Highway559, resulting in its current length. Highway69 passes through significant tracts of wilderness and forested land, and consequently has seen a rate of animal collisions well above the provincial norm. Several segments of the four-laned route will include special grade-separated wildlife crossings, the first of which was completed in March 2012. In the summer of 2012, work began to four lane a segment between north of Highway 64 and the Murdock River, as well as on a segment between Highway 607 and north of Highway64. The first project was opened September11, 2015, while the segment from north of Highway607 to north of Highway64, including an interchange at the latter, was opened by the beginning of August 2016. The most recently completed section as of 2023 was a segment from north of Highway522 to north of Highway607 that opened on December23, 2021. Future Although the original plan called for the four-laning of the highway to be complete by 2017, the timeline was pushed back due to delays in environmental assessments and land negotiations with First Nations bands impacted by the construction. In the early 2010s, a widespread perception that the project appeared to be falling behind schedule was frequently discussed in Sudbury's media and by candidates in municipal and provincial elections, but the Ministry of Transportation continued to assert that the project was on track for completion in 2017. In March 2015, the ministry officially acknowledged that the 2017
