With the four-day bank holiday weekend underway, motorists faced congestion at travel hotspots throughout Hertfordshire.
On Thursday, June 2, drivers faced disruption on several main routes, including the M25 and M1 motorways in the St Albans, Cheshunt and Watford areas.
Rail lines in London were reportedly busy, and rail firms advised passengers not to travel to The Queen's Platinum Jubilee viewing areas in central London due to crowding.
According to National Highways' Traffic England website, the M1 was slow moving in both directions on the M1 near Luton, between junction 10 (Luton Airport) and junction 12 (A5120, Toddington) around midday.
There was also congestion northbound between junction 6A (M25, Watford) and junction 8 (A414, Hemel Hempstead).
This was due to a closure to the fourth lane (out of four) on the route following a broken down vehicle at around 11.30am today.
Both incidents have since cleared.
On the M25, traffic was slow moving anti-clockwise between junction 20 (A41, Watford) and the M40 at Uxbridge.
There were currently delays of around 10 minutes against expected traffic, but this has now cleared, according to National Highways.
The M25 was also congested in both directions between the M40 at Uxbridge and the A3 junction near Woking in Surrey, past Heathrow Airport, which has cleared.
Earlier delays on the M25 between the M11 at Epping and the A10 at Cheshunt have since eased.
On the railways, all lines were blocked at Leagrave in Luton from around 4.30pm.
A Thameslink statement read: "We're responding to a trespassing incident in the Leagrave area.
"At the moment, all lines through this station are blocked.
"We're working with Network Rail and the emergency services to remove the trespasser from the railway.
"Until then, your journey will take longer than usual but we don't have an exact estimate of how long this may be."
The line reopened at around 4.47pm when the trespasser was removed.
Several rail firms, including Thameslink, urged passengers travelling to The Queen's Platinum Jubilee parade to "avoid the area" around Buckingham Palace and St James's Park.
A Thameslink statement this morning read: "Our friends at The Met Police have informed us that viewing areas in central London for the Queen's Platinum Jubilee celebrations are now full.
"To avoid the disappointment of not being able to enter the viewing areas, please avoid the area."
There were minor delays on the Northern line in north London, between Edgware and Golder's Green.
This was due to a signal failure at Edgware, with a good service on the rest of the line.
The Victoria line was temporarily suspended earlier today for emergency engineering works.
Good service has since resumed.
The Waterloo and City line is closed on weekends and bank holidays.
Network Rail, which runs several major stations including London Euston and London King's Cross, is warning passengers that trains are likely to be busy over The Queen's Platinum Jubilee weekend.
"If you're travelling over the Jubilee bank holiday weekend, please be aware that trains and stations will be busy," a statement reads.
"Most of the rail network is open, but please plan ahead and check before you travel."
