Calendar view of construction activities, including estimated truck numbers linked here. Dates are subject to change pending weather/other real-world variables. If dates change, the original will have a strikethrough. The new date will be shown after and updated on the monthly development article + construction calendar. Thus far, changes have been minor in the overall scheme of things, and we'll continue putting our best efforts toward maintaining that goal.


Trucking impacts with the * asterisk are semi-truck-sized vehicles, or considered to be heavy impact deliveries, and are required to use the dedicated Dellwood and Alpine routes through the project's duration. All other vehicles will use the best available public roads. Related truck routing articles:
