Annotated map reproduced courtesy of Googlemaps.	This route starts as Hertsmere Meridan 66 BW (formerly Aldenham 66 BW) at Falcon Way (on the parish boundary with Watford), passes under the M1 motorway and follows the old line of the road to join St Stephen 64 BW at the parish boundary with St Stephen. It then continues as St Stephen 64 BW to School Lane, Bricket Wood. There are periodic reports of obstructions placed on the route as it passes under the M1 motorway. Please report these to row@hertfordshire.gov.uk. At the time of the BHS 2021 Access Survey (23 Oct 21), there were two points where bollards prevented wide vehicles, and one place where there was a horse stile. The M1 underbridge has plenty of headroom. There were signs at each end, although the western end shows the old Watford 16 numbering instead of Aldenham 66 (or Hertsmere Meridan 66).

Legal History 20 Jun 1953: This route was recorded as Watford 16 bridleway on the original definitive map. Map DM3-30. The Watford and South of St Albans - Redbourn - Kidney Wood, Luton, Special Roads (Improvements) Order 1958 diverted the 'Bridle Road' known as 'Garston Lane' to the route that uses what is now the M1 underbridge. 'Garston Lane' later became known as 'School Lane'. 31 Dec 1977: The route was shown as bridleway Watford 16, Aldenham 66 and St Stephen 64 on the special review draft map and statement. DM sheet SR-76. The Hertfordshire County Council (Watford 16, Aldenham 66 and Aldenham 80) Modification Order 2005 (confirmed 20 Jun 06) recorded the bridleway correctly in respect of its passage under the M1 and recorded the whole of the Aldenham length as having a width of 5m. (PINS reference FPS/M1900/7/36.) The Hertfordshire County Council (Bridleway 66, Aldenham) (Prohibition of Use by Motor Vehicles and Equestrians) Order 2007 was proposed as a means of stopping motor cyclists (as it would enable barriers to be installed), but was not confirmed. 1 Apr 2023: The Hertsmere Borough Council (Reorganisation of Community Governance) Order 2022, made 29 Dec 2022 and coming into effect 1 Apr 2023, moved the Aldenham Parish Boundary, resulting in this way falling in the new parish of Hertsmere Meridan instead of Aldenham.
