I've faced a problem of displaying tooltip over route with specific information. I've tried infowindow but it did not worked for me. This what i've tried
directionsService.route(request, function(response, status) {
var myRoute = response.routes[0].legs[0];
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
for (var i = 0; i < myRoute.steps.length; i++) {
for (var j = 0; j < myRoute.steps[i].lat_lngs.length; j++) {
points.push(myRoute.steps[i].lat_lngs[j]);
}
}
var eventLine = new google.maps.Polyline({
path: points,
visible: true,
strokeOpacity: 0,
zIndex: 1000
});
eventLine.setMap(map);
google.maps.event.addListener(eventLine, "mouseover", function(event) {
alert('mouseover ' + event.latLng);
// here i want to show tooltip with location got from event (event.latLng)
});
} else {
alert("Directions request failed: " + status);
}
});

You could attach a Label to the line though, e.g. see blog.mridey./2009/09/… – duncan Commented Aug 2, 2013 at 13:01

Reset to default 3Here's a simple working example for you. Everything with the Label is via http://blog.mridey./2009/09/label-overlay-example-for-google-maps.html
Basically we work out the distance half-way along the line, add an invisible marker to it, calculate the length of the line in miles and kilometres, then attach a Label to that marker which gets displayed when we hover over the line.
