Statutory Procedures
For statutory procedure purposes the Birmingham - Nottingham Motorway M42 was divided into 3 sections, namely
- Bromsgrove Section. M5 to Monkspath (Junctions 1 to 4)
- Solihull Section. Monkspath to River Cole (Junctions 4 to 7)
- Tamworth to Castle Donnington Section. This section included the length of the M42 from the River Cole to the Curdworth Interchange (Junctions 7 to 11) and the dualled section of A42
The Line Order for the Bromsgrove Section was published by the MRCU in 1972 and 3 Public Inquiries were held in 1973/1974, 1979 and 1984. The outcome of the inquiries lead to appeals to the High Court, court of Appeal and the House of Lords. The statutory procedures for the whole of the Bromsgrove Section were not completed until 1988.
The Solihull Section of the M42 was included in the trunk Road Preparation Pool in 1968. A Public Inquiry into the Line Order was held in 1972 which lasted less than a week and Compulsory Purchase Order inquiry was held in 1973 which lasted 1 day. Construction started in 1974.
The line of the M42 between the River Cole and Curdworth Interchange was published in early 1970's and was the subject of a Public Inquiry in 1972 with the line being confirmed in 1973. The route of the motorway was the subject of 2 Compulsory Purchase Order Inquiries in 1976 and 1980. The Statutory Procedures were completed in 1982.
The Birmingham - Nottingham Motorway M42 (M5 to Curdworth Section) forms the southern part of the strategic link between the M5 and the M1 south-west of Nottingham. It also provides the connection to the northern end of the London - Oxford - Birmingham Motorway M40 at Umberslade. Along with the M5 and M6 the M5 to Curdworth Section of M42 forms the southern and eastern sides of the motorway box around Birmingham. The M42 - A42 strategic route was completed in December 1989 and London - Oxford - Birmingham Motorway was opened to traffic in January 1991.
Free-flow motorway to motorway junctions are provided at:
- Catshill between M5 and M42
- Umberslade between M40 and M42
- Coleshill between M6 and M42.
Six interchanges give access to and from the trunk and Class A routes crossed by the motorway. At the A45 T Interchange (No. 6) access to the National Exhibition Centre is provided.
The M5 to Curdworth Section M42 is 27 miles long and has a dual three lane carriageway with dual two lane slip roads at the M5 - M42 junction at Catshill and the M6 - M42 junction at Water Orton. The motorway and slip roads have a flexible black-top surface except for the Alvechurch Section and part of the Umberslade Section which have a rigid-concrete surface.
Over a hundred bridges carry the motorway over or under side roads, railways, canals and rivers. There are seven railway bridges, one of which was constructed to carry the railway over the motorway before the start of the construction of the Solihull Section.
The motorway crosses the Worcester - Birmingham Canal north of Alvechurch and this necessitated a 450m long diversion of the canal to accommodate the motorway.
Details of the various sections of the scheme, in junction order, follow.
Alvechurch (J2 to J3) and Umberslade (J3 to J4) Sections
The second section of the M42 to open was the Umberslade Section in 1985 and this section was the first of 3 sections at the southern end of M42 which were constructed during the period May 1983 to June 1986. The construction of the Umberslade and Alvechurch Sections was undertaken by the same Contractor, Dowsett Engineering Construction Ltd.
Together the two contracts included the construction 8.7 miles of dual 3-lane motorway, half of the M40/M42 junction at Umberslade, two interchanges and 19 bridges. During the tender period the Contractors were instructed to price both the cost of a flexible black-top pavement and a rigid concrete pavement. On both contracts the construction of a concrete pavement was the cheaper alternative. Of the 2 contracts Alvechurch was the smaller. It was 2.4 miles long and included the construction of 5 bridges. It was completed well within the contract period.
The Umberslade contract was 6.3 miles long and included the construction of 14 bridges, 2 of which were over a railway line and a canal. The contract got off to a slow start as the first 2 months were very wet and this delayed the start of the earthworks. This delay had a knock-on effect on the subsequent operations and the contract finished 20 weeks late.
Both contracts have a rigid concrete pavement. The pavement is unreinforced concrete 300mm thick with transverse joints at 5m intervals and a longitudinal joint down the middle of both carriageways. The concrete pavement was slip-formed using a paver incorporating a device which automatically placed the contraction joint dowel bars into the fresh concrete while the paver was moving forward. This process had not been used before in this country and probably accounts, in part, for the roughness of the ride.
