What is a feasible long way transportation system with technology up to 1699?

Exposition

One of the biggest Problems my Renaissance city with 2.7 million inhabitants is facing is how two get food from outside the city fast enough to the populous before being spoiled.

The problem is that in the last few decades the city has grown bigger than what the surrounding area can provide and as such the city is in dire need of a long range (200 - 500 km) transportation system that is able to transport enough food every day to provide for 2.2 million people (the other 500 000 are feed by the surrounding area). The city density is 8000 people per $km^2$.

Needed:

• Full land transportation (there are no seas or oceans to use as transport route)
• Fast enough to transport fruits like apples, pears, ... (before being spoiled)
• Works all year long (independent of seasons)
• Can transport all kinds of food
• Requires knowledge from 1699 or before
• No conservation techniques required

Optional

• Fast enough for meat transportation (before being spoiled)
• Can be used to transport anything
• Requires less infrastructure than an aqueduct
• Cooling
• Infinite range
• Fast enough for milk transportation(I highly doubt this is possible but it would be awesome)
• Achievable with medieval technology

Question: I want to know whether this is possible and if yes how the solution would look like.
