Here's a bit more information on the lanes you posted:
SP1670-8a Seams OK to drive
Nice easy route for the Freelander, we were followed through by a small Fiat so definitely suitable for all vehicles
Lovely lane with a nice bridge over the motorway. Bit scratchy in places but nothing serious. Some lovely fords at one end.
SP1570-5a Seams OK to drive
Entrance to this lane is signposted by the Warks c.c. white disc system. Hard turn of the main road and straight into a stiff climb, Known locally as "THE STEPS" due to the way the lane drops down the hill, I.e; drop, level, drop, level. Very rutted, tow bars catch out. Hedges over grown could be very hard to drive in winter due to the steepness of the climb back up the hill..
Great on a bike, but very rutted from 4x4s, fairly steep climb up from the stratford rd, then drops down the other side gradually, lapworth gun club at the other end.
Had a less than cordial exchange with the LO of the buildings at the SP 1640 7010 end who seemed to think we ought to find something better to do with our time.
SP1869-3a DO NOT DRIVE
Bartholomews 1927 map shows all this lane including current bridleway part as 'road passable for cyclists'
TRO on old canal bridge too weak for vehicles (apparently)
Dick's Lane is subject to two permanent TRO's. One covering the canal bridge section. The canal bridge is an old wooden structure and is a listed sturcture. It has a weight limit of 2 tonnes when in restored condition. The other permanent TRO covers the rest of the route. There is a DMMO in for the section of Dick's Lane that goes past Brome Hall to upgrade to BOAT I have no idea what effect this will have on the sstatus of the rest of Dick's Lane.
SP1766-1a Seams OK to drive
Easy entrance at SP177673, by some white railings. cross a small ford, then slight climb into tree line. this turns into a hedge / tree lined tunnel. mud track but firm. ends on tarmac track at SP176665, where the houses start.
If this route is not on List of Streets it almost certainly should be but Warwickshire appear to have managed to not get their publicly maintainable roads shown as ORPAs by the OS.
Will need an eye kept on the tunnel of trees to prune them back. As it's local to me I'll cover it on my month drive
