Road closure needed for tonight.

It’s a Highways England closure so Closure Monitor ought to pick it up. I’ll try to remember to check this evening.

Upon further investigation (on roadworks.org) it looks like it’s only closing one lane of the slip road. So Monitor shouldn’t pick it up - and it hasn’t 
Hi Ian
I tried to join the A303 at this location this evening and it was closed, I decided to after you saying it was only one lane to risk it - had I followed my gut instinct I’d have headed out on the M4 - this added 1 hour to my journey by going this way.
I’m guessing the reason the Highways England closure / Closure monitor didn’t pick it up was that it was just the ramp that was closed. Interestly when I swapped to Google Maps this Ramp / Slip Road was closed -
Where are they getting their data feed from… I thought it was via Waze !!!

Sorry to hear of your delay.
It’s sad that Highways England can’t produce consistently reliable data. The entry - from data HE provided - on roadworks.org seemed quite clear when I looked at it, only one lane closed, not the whole slip road. Unfortunately it’s gone now so I can’t go back and check.
I’m guessing that the feed Monitor looks at looked the same as roadworks.org - only a lane closure and not a full road closure.
Monitor does frequently close slip roads, and not just on motorways. Here is an A303 slip it closed last night.
Obviously we can’t close whole roads when there’s just a lane closure, otherwise we’d shut half the motorway network each night! I don’t think there’s anything to be done except bemoan the unreliability of HE data - while still acknowledging that it’s right enough of the time to make it better to use than to ignore it.
