Motorring 4
road in Denmark
Motorring 4 (O4) is a motorway ring road that runs from Ishøj to Ballerup. It is followed by Ring 4 which goes on to Kongens Lyngby. The motorway connects the motorways Køge Bugt Motorway, Holbæk Motorway and Frederikssund Motorway.
In November 2003, a majority in the Folketing agreed on a traffic package, which meant that the drafting of a decision-making basis for expanding the motorway from 4 to 6 lanes had to be initiated. In July 2009, a significant part of the decision-making basis for a construction act was completed for approx. 4 km long stretch between Motorvejskrys Taastrup and the connecting facility between Motorring 4 and Frederikssund motorway. The expansion was to be completed in about 5 years, of which the last 3 were construction work. The motorway was laid out with an extra-wide central relief with trees, which should tie the forest landscape together across the motorway. Therefore, the expansion can be carried out by extension with tracks in the existing central rebate.

Why this record matters
“Motorring 4” is worth following because a concise public description often conceals a longer documentary argument. Here, Motorring, road and Denmark provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 8, 2025. The linked authority identifier is Q2199448. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2003 and 2009.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
