LBM: Expansion of the L138 between Niedermennig and Konz
The State Mobility Authority (LBM) Trier announces that On Thursday, September 10, 2026, the expansion of state road 138 between Niedermennig and Konz will begin. Construction will begin. The project is a state-funded undertaking of Rhineland-Palatinate and will cover a length of approximately 3.1 km.
The road resurfacing costs amount to approximately €1.1 million and are being borne by the state of Rhineland-Palatinate. The construction project is being financed by funds from the Federal Republic of Germany's special fund for infrastructure and climate neutrality. The contractor is dittgen Bauunternehmen GmbH from Schmelz.
The construction project is divided into two consecutive phases. Due to the narrow road widths and the necessary excavation work, the work can only be carried out under a full road closure to protect road users and construction personnel, and in accordance with nationwide regulations.
The upcoming first construction phase will take place between Niedermennig and the junction of the district road 136 to and from Kommlingen over a construction length of approximately 900 m in a construction period of approximately 2 weeks.
The second section will follow immediately adjacent to the first construction phase. This section extends from the junction with K136 to just before the village of Konz, covering a length of approximately 2,200 meters and taking about four weeks to complete.
The existing road cross-section is reinforced by replacing existing asphalt layers.
In addition, as part of the project, the shoulders on both sides will be reconstructed, farm tracks will be adapted to the new elevations, and the roadside drainage facilities such as culverts, manholes and swales will be partially renewed.
A detour route will be set up.
The detour is via the L138 to Nieder-/ Obermennig and Krettnach - L139 - B268 – B051 – K134 - Konz and L138 and vice versa.
Further information and details regarding the diversion route will be provided shortly by the transport authority in the Rhineland-Palatinate Mobility Atlas at [link to map]. mobilitaetsatlas.de Provided (activate the detour route in the side menu under "Settings").

The entire project is expected to last until the end of October 2026.
Regarding bus services:
During the construction period, lines 292 and 293 will have to be diverted over a wide area; line 292 cannot operate on its usual circular route through the Konzer Tälchen.
The Line 292 The bus runs from Konz via Kommlingen, Oberemmel, and Krettnach to Niedermennig, terminating at the Heinertstraße stop. From there, it returns via Krettnach, Oberemmel, and Kommlingen to Konz. In particular, school bus services from Oberemmel Elementary School will initially run to Niedermennig and then return directly to Kommlingen and Konz without requiring a transfer. During the full closure, through service between lines 292 and 290 to Wawern and Saarburg will not be possible.
The Line 293 The bus runs from Pellingen via Krettnach, Oberemmel, and Kommlingen to Konz. Service to the districts of Obermennig and Niedermennig is provided by route 292. Route 293 requires more time for this route; therefore, journeys start earlier in the morning and arrive later at midday – the reverse applies.
Individual journeys of the Line 290 Due to the longer travel times of lines 292 and 293, adjustments will be necessary.
