The longest straight road in Estonia?

I looked around on Google Maps and saw that, for example, in Tallinn, after Tähetorni St. from the parking lot of the Harku health trail, there is practically a direct route for several kilometers. Hence the question: what is the longest direct road in Estonia that can be driven in public? (In Maps, this particular section can be traversed in “walk” mode, as there is a quarry in between)
