@NNN I assume credit belongs with the Minneapolis Public Works department for designing/implementing policy in accordance with the Transportation Action Plan, Strategy 9.

Public Works charges increased fees for bike and sidewalk lane obstruction permits. The intent is to incentivize contractors to reduce the extent/duration of the obstruction and prioritize desired modes.

The policy/pricing was last updated in 2023. Current prices listed in the first image; historical prices in the second image (note that the proposed prices in the second image were amended by city council before passage).

Assuming this pricing was applied to the ~2600ft of the Greenway (between the nearest bike-accessible intersections), it would cost the contractor $1560/day to close the two bike lanes - at which point, it may be cheaper to keep the lanes open and pay flaggers.

EDIT: Updated, re-calculated prices for the Nicollet Avenue. Originally, had calculated for 10th Avenue by mistake.
