Lord Berkeleyasked Her Majesty's Government: Which regulations cover the provision of road crash barriers at bridges crossing over railway lines; and whether Department for Transport papers H9/ 73 or TD19/85 are still in force. [HL4606]
§ Lord Davies of Oldham:The current Highways Agency advice note that covers the provision of road safety barriers at bridges crossing over railway lines is the interim requirements for road restraint systems (IRRRS). This advice note was introduced in July 2002 as an interim advice note to the Highways Agency's design manual for roads and bridges. This is mandatory for trunk roads and commended to local highway authorities.
TD 19/85 remains in force only for minor safety barrier replacement works. It also remains in force for schemes already under construction, and those under preparation at the time of issue of the IRRRS, where a change to implement the IRRRS would have resulted in significant additional cost or delay.
Technical memorandum H9/73 is no longer in force; this document was superseded completely by TD19/ 85.
