Project Summary:

As part of SMP Alliance’s delivery of the safety enhancement programme between Junctions 10 and 13 of the M1 for National Highways, essential upgrades have been made to the central reservation to improve safety and resilience for all road users. Located near the busy Luton Airport junction, this high traffic stretch of road required replacement of existing steel barriers with safer modern concrete alternatives. Balfour Beatty, the SMP Alliance on-site assembly partner for this scheme, led delivery of the works, with Hill & Smith Infrastructure playing a key supporting role. Hill & Smith supplied and installed temporary barrier systems that enabled essential drainage, earthworks, and structure upgrades for project operations to progress safely and efficiently. 

 

The team has faced several challenges: 

High traffic volumes 

Junction 10 of the M1 serves as a key access point to Luton Airport, making it one of the most heavily trafficked sections of the motorway. Any closures in this area had the potential to cause major disruptions. 

Limited working windows 

Due to the high volume of traffic, particularly during daytime hours, the majority of construction activity was confined to overnight shifts. 

Complex stakeholder environment 

The project corridor included access routes to major distribution centres operated by Royal Mail and Amazon, making stakeholder coordination an essential component of the project. 

Tight programme constraints 

The project team faced pressure to deliver an 18.9km central reservation concrete barrier upgrade within the mandated completion timeframe, on a live motorway, with minimal disruption 

Barrier transitions across bridge decks 

The project included several bridge decks where standard barrier solutions were not sufficient, requiring carefully specified transitions between systems.
