2. Design and construction of accommodation traffic lights at the pedestrian crossing in the village
Adamowizna, municipality of Grodzisk Mazowiecki, Powiat Grodziski.
The subject-matter of the contract is the task of drawing up project documentation and, subsequently, the construction of traffic lights at the existing pedestrian crossing in Adamowizna, in the school area. This section of road 1505 Grodzisk Mazowiecki – Józefina – ul. Osowiecka is located in the Mazowieckie Voivodship, in the county of Grodzisk Maz., in Adamowizna.
Traffic lights shall be performed in the designed road geometry.
The project is located in an area not covered by a local land-use plan.
The section of the road is intended for conversion.
