Digging around to find out more about this bridge I found this news video about a car crash here. Interesting that it was reported that the ‘motorist hit the pillar and ‘man collides head on’ Not ‘car hit the pillar’ or ‘car collides’

The Stadspark in Groningen is an approximately 140-hectare park on the southwest side of the city in the Stadsparkwijk.
The construction of the park was an initiative of the Groningen industrialist Jan Evert Scholten and was inspired by the ideas of the City Beautiful movement.
In 1909, Scholten founded the Vereeniging Het Stadspark with the aim of raising money for a public park. Work started in 1913. The park was designed by the landscape architect Leonard Springer, together with the Groningen director of municipal works J.A. Mulock Hack.
Construction work was carried out by unemployed people as part of the job creation. The official opening of the Stadsparkpaviljoen, centrally located in the park, took place on 19 May 1926. With that, the construction of the park, which had taken thirteen years, was completed.
The park is built in a low-lying, swampy peat area that is covered with a layer of clay and sand.

You can see the swampiness in this pic from 1945 of a German trench line in the Stadspark at the time of the Liberation of Groningen.
One of the most notable features of the Stadtspark is this horse racing track or Draftbaan.
Another centre piece of the Stadspark is the paviljoen.

In 1915 a competition was held for the construction of a pavilion, which was to serve as a coffee and tea house and a concert and meeting room.
There are a lot of sports facilities available in the park - including disc golf.
Here's a map of the disc golf course
Other sports facilities in Groningen's Stadspark include a competitive athletics track and and football pitches
About 5km south west of the city centre is th Hoogkerk park and ride. Parking is free and you can choose to take the bus or hire a bike.
The bus costs 6 euros (for up to 5 people) for return trip to the city. If you are traveling alone, a Euro ticket or the use of the OV chip card is cheaper.
Travel time to the city centre is about 20 minutes.
The first part of the route is for buses and bikes only
Seeing that this park and ride is only 4.5km from the Groningen city centre you could always hire a bike from DeelFiets for € 2 per hour, with a maximum daily rate of € 12.
It's only a 15 minute bike ride into the centre.

There is also a hotel conveniently located at this park and ride - with ample cycle parking and a cycle path right outside the front door
Of course you can also leave your own bike at this park and ride - there's plenty of cycle parking.
There are 6 other park and ride stations dotted around the outskirts of the city including one near the main train station.
There are three train stations in Groningen:
Groningen Noord, Groningen Station, and Groningen Europark
Here's Groningen Noord which lies just north of the city centre. It has ample cycle parking and connections to buses and bike paths
Two trains an hour going north to and from Roodeschool and Delfzijl
travel through Groningen Noord station
Here's a cool video from @Train_viking about the ongoing renovations of Groningen Main Station as well as the
Groningen - Eemshaven - Borkum (Wadden Sea island) train & ferry from the Netherlands to Germany
This snapshot of the national rail network shows where Groningen sits in the regional and national rail networks
Zwolle is about 100 km away and you Google says you can cycle there in 5-6 hours.
Or you can get there by train in about an hour for a cost of €19.30
Leeuwarden is about 62 km away. You can cycle there in 3 or 4 hours or take the train in about 50 minutes for €10.97.
Say you were travelling to Groningen from somewhere further afield like Rotterdam - which is 240 km away in the south west of the country - you can take a direct intercity train in 2 hours 37 minutes and it'll cost you €27.40
single way, 2nd class, full fare.
This panel on the train company website is particularly useful as it tells you what shops and services will be open upon your arrival in Groningen - and how many OV Fiets bicycles are available for hire.
Here are all the OV Fiets bicycle rental/hire locations in Groningen
By 2023, the central train station in the city of Groningen will be getting a major makeover. Here is a preview of the current design plans.
Main station Groningen seems to be a very modern station. Practical layout, bicycle tunnel, open on two sides, many shops, mega-sized bicycle shed underneath, extra platforms and lots of light.
Anyone know what's happening to this rail yard?

To me it looks like a lot of this is going to be removed to create this new subterranean entrance.
Worth running this article about sand removal/cleaning thru google translate.

Look like the answer to my previous tweet is a yes.

If you didn't come to Groningen for a while, would you still recognize the main station?
