Safe bike route from Millvale to Homestead that I use. To get from Millvale to 40th St Bridge, use sidewalk on ramp, rather than biking in the road, and east sidewalk of bridge. Route goes thru Allegheny Cemetery. Note that car gates are closed around sunset, but there are always pedestrian gates open that you can walk your bike through. Near Homestead Bridge, definitely use east sidewalk on Brown's Hill Rd, on bridge, and on ramp down to Amity.
