The sections west and east of Jerusalem are linked by an expressway segment running north of the city centre.
Known internally as Yigael Yadin road or 'Jerusalem Road 9', the stretch has divided lanes, but includes several at-grade intersections alongside its interchanges.

In 2001 Moriah, the Jerusalem Development Company, started building a bypass of the city's oft-congested western entrance, designated as 'Jerusalem Road 9'.
Before it was built, travelers from west of Jerusalem who wished to reach the Dead Sea, or vice versa, had no better option than to drive through congested city streets.
The road was intended to improve traffic flow in Ramot and nearby neighbourhoods.

The 3.6 km road descends from the purpose-built Sha'ar Moriah Interchange to allow continuous separate grade access to Yigael Yadin Interchange and the northern and eastern continuation of Highway 1.
Passing through Emek HaArazim (Valley of Cedars), it includes two 400 meter tunnels (one for eastbound traffic and one for westbound), four bridges over the Sorek stream and two new interchanges.

While the highway was scheduled for completion in early 2005, work was slowed to a near halt between 2003 and 2006 and completion was postponed for over two years.
The opening, planned for May 21, 2007, was postponed another two months due to Moriah's failure to complete the required environmental mitigation.
Permission to open the road was granted on condition that the company and Jerusalem municipality guarantee completion of environmental mitigation after the opening.
Road 9 opened on July 25, 2007 and constitutes part of Highway 1.

In October, 2014, Jerusalem Road 9 was officially renamed "Derech Yitzhak Shamir" after Israel's 7th Prime Minister.
