The bridge reopened at around 10:30am, operator Øresundsbron wrote on Twitter.
A closure in both directions was caused by an accident on the bridge, according to the operator's Twitter account.
The accident involved a single lorry that lost control and collided with the central reservation, Copenhagen Police confirmed. No injuries occurred.
The Danish Road Directorate wrote earlier on Wednesday that it did not know when the bridge would reopen, but traffic is now set to begin moving again.
