Historic Main Bridge in Marktheidenfeld to Close for Major Repairs
The two-and-a-half-year closure will completely halt traffic for motorists, cyclists, and pedestrians starting in early 2027.
The historic Alte Mainbrücke in Marktheidenfeld is scheduled to close completely for approximately two and a half years to undergo extensive renovations starting in early 2027. Daniel Philipp from the State Construction Office outlined the upcoming project during a public town hall meeting, explaining the necessity of the closure for motorists, pedestrians, and cyclists alike.
Construction is expected to begin in February or March 2027 and last until the summer of 2029. The timeline is highly complex because work on the interior of the bridge arches relies on coordinating with annual navigation pauses on the Main River, periods when locks are repaired and commercial shipping comes to a temporary halt.
During the entire construction period, the bridge will be entirely closed to all traffic, including cyclists and pedestrians. Construction equipment and materials will be stored beneath the bridge, requiring the closure of local pathways. Cyclists will be directed along a designated detour starting from the inner city, passing the bridge parking lot and the Hotel Zur Schönen Aussicht before returning to the riverbank path.
The renovation project focuses on renewing the upper, modern section of the bridge. The roadway will be refurbished and elevated by roughly twelve centimeters, while the pedestrian and bicycle lanes on both sides will be widened and positioned to overhang the bridge structure to protect the underlying natural stone. Additionally, new street lighting and an upgraded railing designed to withstand heavy vehicle impacts will be installed.
Stone restoration experts will handle the historical components of the bridge, replacing select stones and renewing mortar joints without significantly altering the structure's appearance. Meanwhile, the steep and narrow staircase leading from the parking lot to the bridge cannot be preserved and will be rebuilt in a longer configuration to accommodate the elevated roadway, though a barrier-free ramp is deemed unrealistic due to spatial constraints.
Addressing safety concerns, officials noted that the bridge currently holds a passing grade equivalent to a school grade of four based on regular state inspections evaluating structural safety and durability. The total cost of the project is estimated at five million euros, with the federal government covering the vast majority of the expenses since the bridge functions as a federal highway.
The city has decided to use the construction window to independently finance and update utility lines running through the structure. During local events such as the annual fair, the construction office plans to clear the area beneath the arches to ensure festivities can proceed without disruption.
