I-89 Bolton and Milton Interchanges Assessment

5.4 MB
Year:
2022
Theme:
Interchange, Interstate
Description:
Born out of the I-89 2050 Study, this assessment reviewed two interchange concepts, one in Milton near the West Milton Road bridge over I-89, and one in Bolton near the Bolton Valley Access Road. Both locations have previously underwent some form of study. However, the previous studies date back to the late 1980s/early 1990s. This assessment served to review modern geometric design standards and environmental requirements as they pertain to each conceptual interchange.
