A pay dispute saw construction workers block the main route to the Arena Gdansk prior to the Euro 2012 match between Spain and Croatia.
Sub-contractors claim general contractor Hydrobudowa has withheld payment for building a road which links the stadium to Gdansk airport.
Protestors held aloft banners asking ‘Euro 2012, but at what cost?’, with up to 100 different contractors demanding payment of approximately 12 million euros between them.
The workers did allow fan buses access to the stadium, where Spain defeated Croatia 1-0 to secure top spot in Group C on Tuesday.
Tournament organisers will be hoping to avoid a repeat of the disruption when the Arena Gdansk plays host to the quarter-final between Germany and Greece on Saturday.
